Firstly, you should find potential investors and then pitch to them your idea. Or you can choose to acquire the knowledge you need to make your "unique & awesome" business idea a reality first then build it up yourself. Don't buy a domain and hosting yet until you have a solid plan and investments.
We don't have much to say or suggest because you did tell us what's your idea about (even though your post is so long).
(Sorry for the self-promotion, if you'd like to pitch you idea and ask for investment, you can do so at TBZ's
Raise Investment (external link)).
I can't suggest him to find an investor for this early stage, his site doesn't guarantee to earn fast success if he can habe investor beside him and i doubt his legitimacy and sick to see som newbie who's offering that, and the only thing he must do for now is to became more informative to tell some proper details about this plan and he must have fundings for here own and make his site successfull first before asking some investors to invest at him so that people have assurance that they can earn and will not be scammed.
