I have similar desires to qisine (though younger and a bit better with pointers), and realise that I need a market myself, but can't find anything that I can do that people would be willing to pay for, or not find an already existing alternative.
Look, anyone is ready to pay for what they need. So instead of finding something people are willing to pay for, start by finding something people NEED (=> solve a problem).
Cash will come on its own ;)
