sorry. had to go there.
Really though, private investors are the way to go. You should really patent it though. I would say get all your info from http://www.uspto.gov/. Though there's always disputes on ownership/violations of copyrights, at least you can fend off the small guys. Also, though you've probably already looked, you should be able to find out if your idea conflicts with something that's already been patented. Good luck!
