Does anyone know a good source for VC –Venture Capital- or AI –Angel Investors-?

I have an idea of a potential product not available in the market yet. I Google it and couldn’t find anything like it. I run it across some friends and they all think is a good one. Has anyone use any of these investors? How did they turn out to be? Can you provide feedback as our own experience? I have done some research and all the ones I have found out require a massive master business plan in place. Do you have a source for a place where they have a template for writing an acceptable business plan?
