I think, closest to answer is scientific marketing. It will answer to two questions: first, what people looking for now, second, are these people ready to pay for this thing. I believe, I should not prove you so obvious things. Many famous people claimed, they don't use scientific marketing (most known example Jobs), but when insides leak from their closed circle, all people ho learn marketing clearly seen, they do almost same as classic University marketologist, just name things other names. Sure, you could save about 100$ on classic marketing research and do things yourself. It is even possible, doing things yourself, you will got more clear and more reliable data on your case. BTW exists many books on how to stay small in business, and have good enough economy (everybody don't need to become Google to succeed). Any way, most powerful business heuristic - Just do it, don't wait, don't procrastinate, do not doubt, do and calculate results and only then think on results.
