Where to start?

So I want to learn an aspect of IM that A) lots of people are interested in, and B) can help lots of businesses. What I learn, I plan to monetize it within a very affluent East Asian market which is a few years behind that of The West in terms of IM. I'm certain that there is money to be made due to this time lag in IM practices.
Right now my knowledge is rather sporadic so unable to make an informed decision; will be grateful for any suggestions.
