Hello everyone this is my first time posting and I must say I'm really happy I found invaluable website.

I am currently writing a business plan for an idea I have but I'm unsure of how to obtain the financial figures to show how much the business can make.

My business will be a website based on a social networking platform. The primary source of income will be through targeted advertising and sale of market/trend data(which there will be a lot of).

I am finding it very difficult to find the right person to talk for a rough estimate. I have no market research to show the projected hits my business will make.
I have been looking for is a rough estimation of the projected earnings based on the type and amount of information sold and commission made on sales through ads based on certain levels of hits made through my website.

My main problem is that the only people who can give me this information are essentially competitors. This means I cannot put a price on my primary source of income.

What I would ideally be looking for is an individual or organisation to look at our business model and work our the projected earnings.
Otherwise I would be happy with some rough estimations.

Thanks
Stuart MacMillan
