Hello, I'm Stefan, live in Romania, Europe, and have 8 years experience working in accounting, audit and financial advisory.
Please look at the files I sent and the ones attached to my profile - they detail my approach in terms of model building of costs, revenue streams, revenues, financial statements forecasts and scenarios. You can collapse or expand by clicking the group/ ungroup buttons (+ or - signs on top of spreadsheet).
I have extensive experience in business modelling and can send other samples, from various projects I had (different industries); the mentioned samples are built around the same model ( usually respects the core elements); also have few projects with simplier/ easier models.
I've built models for existing businesses and start-ups with multiple products and revenue streams and worked as an accountant, junior auditor or consultant for service sector (web development, water supply and waste water management, architecture, retail, financial services) and manufacturing companies (garments, furniture, oil products, iron casting and metal works, barite ore mining, cardboard packaging). In hotel & restaurant industry I also produced linear optimization for price-product mix.
It will take me between 2 to 3 days (10-15 work hours), depending on data I have to search and I will build the model in one excel file and 3 scenarios, so you can compare "What if scenarios" and plan ahead your next moves.
