Please help with this question. Business Question??? Inventions??? Investors?

Besides going after investors on the 'Shark Tank' show.....is there any other investors out there that might invest in a really great original invention? I have really great inventions but I have zero capital and no means to get my inventions off the ground. I was wondering if there were trustworthy businesses out there that do this kind of investing?? Please help in answering this question or give any advice. I'm tired of being poor & sitting on these great inventions of mine.
