You'll need qualified experts to look at each concept to make initial determinations as to whether or not in idea can pan out. It's often said that ideas are cheap, and dumb looks are free.
As an investor, I have a procedure that I follow each time I'm considering a new venture. I call it the "Stink Test". I spend up to 90 minutes using my research tools, my knowledge, experience and common sense to look deeply into a proposal. If I've not turned up my nose at that point, I tell the applicant that they passed the stink test, and that I'm interested in pursuing further relationships. If my nose is red... it's over.
I've examined over 200 prospective ideas over the past 3 years or so. Remember I said *up to* 90 minutes. Out of the 200+ "sure things" 4 managed to hold my attention. I'm pleased to say 2 are selling, 1 decided that there was insufficient $$$ to be made, and the other is still burning the midnight oil.
