High, this is my first posting and i was after some advice. So here goes. I am currently writing a business plan for an I.T. startup that is web based (utilising broadband services). However my problem is revenue forcasting. There is currently no model or competition i can use to guage my forcasting on, and i belive this is a rather important part of the business planning process. I could put a finger in the wind and hope for the best but it could be an order of magnitude out. Please help, any advice would be very welcome.
