Handmade Jewellery — Recycled Silver, Taken Online
Handmade Crafts / E-commerce | Engagement began: 2020 or later
The Brief
Petrina worked with a craftsperson making handmade jewellery from recycled silver cutlery, designing the operational setup needed to take the business online.
The Approach
Petrina built out the online operations for the business, giving the craftsperson a proper e-commerce presence to sell a distinctive, sustainability-led product.
RESULTS
Moving online increased sales by 48%.
Garden Rooms — From Bespoke Builds to Department Store Listings
Garden Rooms / Outbuildings | Engagement began: 2018
The Brief
In 2018, a client building bespoke, high-quality garden rooms wanted to expand beyond one-off custom builds into a wider retail presence — specifically through luxury department stores rather than mass-market retailers, sold via an online catalogue.
The Approach
Petrina designed the route to market for the expansion, positioning the product for luxury department store partnerships and an online catalogue presence, rather than a supermarket or mass-retail approach.
RESULTS
The client successfully expanded into other sectors, including several department stores.
Salt Mine Operations — From Acquisition to Export
Mining & Export | Engagement began: 2017
The Brief
In 2017, an established business owner acquired a salt mine in Pakistan and brought Petrina in to help build out the operational side: mining, selling, and exporting the product.
The Approach
Petrina enlisted a team of professionals to help build the required infrastructure, and arranged for the necessary machinery to be imported into the region, navigating the security and customs controls required for the operation. She also secured an investor for the venture. Once the operational and funding foundations were in place, Petrina handed the model over to the client to execute.
RESULTS
The client successfully took the model forward and ran the operation, before stepping back from the business.
Green Clay Deposit — From Beauty Tubs to an Aerospace-Grade Discovery
Mineral Resources | Engagement began: 2017
The Brief
The same client from the salt mine venture acquired land containing a hill of green clay, initially planned for wholesale beauty tubs aimed at the cosmetics industry. When progress stalled, Petrina was brought in to find out why — and what the real opportunity was.
The Diagnosis
Petrina requested the chemical lab results for the clay and brought in a team of technicians and specialists to properly assess it, rather than continuing to pursue the original beauty-industry plan without fully understanding the material.
The Approach
Petrina arranged a helicopter survey of the hill to assess the scale of the deposit. The analysis concluded that the clay contained a base chemical relevant to manufacturing and aerospace applications — repositioning the opportunity entirely, from a cosmetics product to a potential industrial-grade material.
RESULTS
Petrina’s role concluded once this assessment and repositioning were complete, with the findings handed back to the client to pursue further. As with the salt mine venture, the client later stepped back from the business, and Petrina is not aware of what happened afterward.
Football Cafeteria Supply — A Food Framework That Scaled Internationally
Food Supply / Manufacturing | Engagement began: 2015–2019
The Brief
Petrina designed a framework to supply good-quality food products to football team cafeterias across the UK.
The Approach
Petrina built the operational framework needed to supply teams consistently and at quality, giving the business a scalable model to grow from a single supply arrangement into a wider manufacturing operation.
RESULTS
The framework worked: the business went on to supply various football teams with their food product, doubled the size of their factory, brought in bespoke machinery, and has since exported internationally.
Holiday Park Ownership — A Route to Ownership Without Heavy-Interest Finance
Holiday Parks / Leisure | Engagement began: 2026
The Brief
A holiday park owner in Kent wanted to make ownership more accessible to holidaymakers, without pushing them into heavy-interest finance to get there.
The Approach
Petrina designed a system allowing more holidaymakers to become owners without relying on high-interest finance products.
RESULTS
The system is currently going through the client’s legal team for review, given the regulatory implications of effectively creating a financial product — and the need to manage the relationship with their existing funding partner carefully. This engagement is in progress.
Distillery — From Redundancy to a Multi-Stream Business
Distilling / Spirits | Engagement began: 2023
The Brief
In 2023, a couple who had been made redundant wanted to start a distillery. Petrina designed the blueprint, business plan, and operations to get them there.
The Approach
Petrina built out the full foundation for the business — from the initial blueprint through to the operational plan needed to actually run a distillery.
RESULTS
The distillery launched to strong popularity and went on to secure investors. The business now runs on multiple revenue streams: trading at festivals, and renting out their stills to larger distilleries during busy periods.
Household Cleaning Company — Scaling an Established Operation
Cleaning Services | Engagement began: 2025
The Brief
A household cleaning company, already running with 25+ staff, wanted to expand further. Petrina was brought in to design the blueprint and operations needed to support that growth.
The Approach
Petrina built out the blueprint and operational structure to support expansion, covering sales, marketing, and operations as a joined-up growth plan rather than piecemeal changes.
RESULTS
The company successfully expanded its operations across sales, marketing, and ops, building on its existing 25-staff base.
Business Coach — Booking the Right Clients, Not Just More Clients
Business Coaching | Engagement began: 2026
The Brief
A business coach needed more bookings — but the real issue wasn’t volume, it was fit. They needed to be booking corporate clients rather than SMEs.
The Diagnosis
Petrina identified that simply generating more bookings wouldn’t solve the underlying problem; the coach needed a system that specifically targeted the right kind of client for their business.
The Approach
Petrina designed a booking system built around attracting the right audience — corporate clients — rather than optimising purely for volume.
RESULTS
The coach is now booking regularly with corporate clients.
Financial Consultant — A Direct Route to the Right Market
Financial Consulting | Engagement began: 2026
The Brief
A financial consultant needed more bookings. Petrina was brought in to build a system to drive that growth.
The Approach
Rather than a generic marketing push, Petrina drilled down to identify the consultant’s ideal customer base and designed a bespoke system with a direct route to market, built specifically around reaching that audience.
RESULTS
The consultant is now doing well, with a steady flow of bookings from the right client base.
Industrial Unit — Restructuring Instead of Selling Out
Industrial / Manufacturing | Engagement began: 2024
The Brief
A large-scale industrial unit faced a takeover approach from another company — one the workforce was strongly against. Petrina was brought in to find another way forward.
The Diagnosis
With the workforce firmly opposed to the takeover, Petrina recognised the need for a viable alternative path that didn’t rely on selling out to resolve the company’s challenges.
The Approach
Petrina designed blueprints for a way forward that kept the business independent, giving leadership a credible alternative to the takeover.
RESULTS
The company did not sell out and instead restructured, preserving its independence.
Council Care System Audit — Savings Without Compromising Safety
Public Sector / Social Care | Engagement began: 2015–2019
The Brief
Petrina carried out an audit of a council care system, tasked with finding efficiencies without compromising the safety of vulnerable clients.
The Approach
Petrina identified ways to reduce costs within the system while keeping safeguarding at the centre of any changes — ensuring savings didn’t come at the expense of client protection.
RESULTS
The audit identified potential savings of £160,000 per year. The council cited capacity constraints and did not implement the recommendations.

Regulatory Oversight Body — Independent Governance for a Staffing Corporation
Staffing / Corporate Governance | Engagement began: 2020
The Brief
A staffing corporation needed a way to ensure it operated lawfully and fairly, with proper oversight built in rather than relying on internal self-checks.
The Approach
Petrina designed a separate regulatory entity from scratch, complete with its own board, tasked with overseeing the corporation and conducting regular audits and checks to ensure lawful and fair operation.
RESULTS
The body operates on a hybrid model — annual in-person meetings, ongoing online team meetings, and access to quarterly reports, plus the ability to request any further information needed if a problem is spotted.
Online Retail Store — A Small Investment, a Loyal Following
Curated Retail (Vintage, Antiques & New) | Engagement began: 2020
The Brief
Petrina helped build an online retail store from a small initial investment, curating a mix of vintage, antique, and new products.
The Approach
Petrina designed the business to sell across various apps and platforms rather than relying on a single storefront, supported by a small but effective social media presence to build a following around the curated product mix.
RESULTS
The business now turns over regular funds and, while still small, regularly sells out weekly stock. It has built a strong, loyal fanbase across its social media and sales channels.
Training Consultancy — A Hybrid Model That Works at Small Scale
Business Training | Engagement began: 2020
The Brief
Petrina designed a business training consultancy built around a hybrid operating model.
The Approach
Petrina structured the consultancy to run on a hybrid basis, combining in-person and remote elements to deliver business training flexibly.
RESULTS
The consultancy works well at small scale, running successfully on the hybrid model as designed.
Business Rescue Consultancy — Branding a Specialist Offer for Accountants
Accountancy / Business Rescue | Engagement began: 2021
The Brief
An accountancy firm wanted to build a standalone business rescue consultancy, using their existing accounting expertise as the foundation.
The Approach
Petrina developed the branding and marketing needed to position the firm’s existing skills as a specialist business rescue offer, rather than starting from scratch on the underlying expertise.
RESULTS
Client results are confidential given the accountancy context.
Luggage Shipping — Disrupting Holiday Travel Logistics
Cargo & Shipping | Engagement began: 2022
The Brief
In 2022, a startup approached Petrina wanting to disrupt the luggage shipping market — offering holidaymakers a cheaper, easier way to send their luggage ahead of travel.
The Approach
Petrina designed the business model needed to bring the concept to market, positioning it as a lower-cost, more convenient alternative to existing luggage shipping options.
RESULTS
The business is making a fair profit.
Consultant Booking Company — Designed to Franchise
Sales Booking Services | Engagement began: 2025
The Brief
A client starting afresh wanted to build a booking company for consultants — handling sales bookings — with a brand designed from the outset to be franchised.
The Approach
Petrina designed the brand and business model with franchising in mind from day one, giving the client a structure built to replicate rather than a single-site business retrofitted for expansion later.
RESULTS
The business has launched with the franchise-ready brand and model in place.
Contact Centre — Outbound B2B Booking at Full Capacity
Outbound Sales / Contact Centre | Engagement began: 2024
The Brief
Petrina designed a B2B outbound contact centre business, calling from lists on behalf of clients, taking bookings, and updating diaries directly.
The Approach
Petrina built the operational model for the contact centre, structuring it around outbound calling, appointment booking, and diary management as a service for other businesses.
RESULTS
The contact centre is now fully booked every day.
Pre-Contract Due Diligence Consultancy — Beyond the Credit Check
Business Consultancy / Due Diligence | Engagement began: 2024
The Brief
Petrina designed a consultancy offering pre-contract due diligence for businesses — going beyond standard credit checking to cover reputational risk and cultural or operational fit.
The Approach
Petrina built the service around three pillars: assessing reputation and fit alongside financial standing, helping clients negotiate the best possible contract terms, and supporting them through the volume of paperwork involved in getting a deal over the line.
RESULTS
The consultancy has launched with this full-service model in place.
LinkedIn Consultancy — From Hit-or-Miss to a Franchisable Playbook
LinkedIn Training / Consultancy | Engagement began: 2015–2019
The Brief
An established LinkedIn consultant wanted to expand his business but had no set system for training people — results were inconsistent, dependent entirely on his own instinct rather than a repeatable process.
The Diagnosis
Petrina identified that the business’s growth ceiling wasn’t demand — it was the lack of a documented, teachable method behind the consultant’s expertise.
The Approach
Petrina documented what the consultant actually did, turning his knowledge into a structured manual and playbook. Once that foundation was working, she built a business plan to franchise the model.
RESULTS
The consultancy now has a documented playbook and a franchise-ready business plan in place.

Laundry Services | Engagement began: 2021
The Brief

RESULTS
The business is still going strong, now serving 126 clients across Kent.

Wedding Venue — A Full-Service Destination, Built From Scratch
Wedding & Events Venue | Engagement began: 2019
The Brief
Petrina designed a wedding venue business from scratch, built to offer a complete, all-in-one wedding experience rather than a bare venue hire.
The Approach
Petrina built the venue’s full-service offering: venue hire, ceremonies, disco, food, entertainment, parking, and wedding cars, alongside an on-site restaurant and bar that operated independently of weddings, giving the business multiple revenue streams beyond wedding bookings.
RESULTS
The venue maintained steady bookings, hosting around 6 weddings a month alongside other events, before the venue was sold in 2025.
