Financial forecast with scenario analysis & sensitivities for design services startup

I'm setting up a design and branding company. I want to hit the floor running and build up the company as quickly as possible, profitably.

I want a spreadsheet that I can use to show impact of different sales assumptions, where I can hire staff, rent space, buy equipment and so on, in order to justify where these come into the equation.

I've started a bit of a spreadsheet (created tabs and filled in some of the capital expenditure options) but I really think I could do with the help of a professional with experience here to get it done. I am happy to provide information on request.

Please PM me if you have any questions.
