I have built models for all kinds of businesses, e-commerce, manufacturers, Internet services (SaaS), food service, Real Estate, and more. I've developed models for clients in the USA, UK, Australia, and Canada, among others.
My approach is you provide all information, and in 2-3 days I present a draft. I aim to keep the model simple and friendly user.
It depends on the level of detail you need but usually, a project like this, takes from 5 to 10 hours, interacting for about 7 days.
My models include the 3 financial statements (Profit&Loss, Balance Sheet, and Cash Flow Statement), working capital evolution, charts and a dashboard briefing all results on one page. It will be fully automatic so you can change assumptions and try different scenarios. I can build it either on Excel or Google Sheets.
