It seems you have three questions, how do you find who your costumers might be, how do you reach them, and what do you say to them. Keep this separated as it makes easier to research :) I'm going to suggest something for your first question, which is your submission title. How do you identify your potential market? The simplest way is to think what problems you are solving, and then come up with people who have this problem, and preferably who would pay money to avoid it.
