There are many different ways you could approach this. I think talking to people first and getting a sense of what their problems are and doing this enough time to identify the common issues is a good first step. You could use something from the Running Lean book or the Will It Fly Book to layout your idea. Once you know what problems to potentially solve, figure out what is the smallest thing you can do to test it. Maybe its something manual like how the founder of Zappos just start buying shows by hand and shipping them to people if they bought them on the site. If the data from your test shows promise, then work out a MVP and break it up into small chunks you can work against.
