Kickstarter will be your best bet, one product at a time. No need to convince investors, no money to put up, no one to pay back or have control of your company, and it does market research at the same time.

I'd be cautious about approaching investors directly at this point, as others have said you don't appear serious from the guy holding the money's point of view, and once they write you off it is impossible to get a second look.
