Hello,
Excuse my ignorance, but let me see if I understand your request properly. You are looking for busines ideas and will pay for the idea if it is an idea you believe in? Or you will pay for each idea submitted? That said, Sunitia Research has been in this business for a number of years, so let me ask a few more questions:
1. You will have to offer some sort of prepayment to people for this bid. For example, an idea is submitted, what stops you from taking the idea and not paying. For example, one of the companies we just tried to help came to us because they just had 3 ideas stolen from a presentation they gave to a very large international company. The large company took the idea and made a business of it, the small company got nothing besides the pittance we negotiated for them.
2. How do you value an idea? Is it a report with a few business options about a paragraph long - or do you want a full business plan for each idea?
3. It seems that you already have the idea from your example... are you looking for how it should be presented or content?
