financial modelling for a start up in excel

[Sir Snaz]

afternoon all ......

I am just in the process of starting a new endeavor (god I must be mad!!).....and i am looking for a little help/guidance ...our idea has 4 or 5 revenue generating streams .......and I wanted a clean, concise way of breaking these out (maybe in their own tabs?) ......wondered if anyone had any ideas ......or even better could point me in the direction of any templates that I could use?

thanks a million
