Speaking as someone who knows enough of both to break things but is by no means either a designer or a developer, I think that your best bet is to document your idea in as much detail as you can. Be extremely specific. Write down not only what it is, but also how it should function. Split it up into manageable parts and and work on getting a prototype created.

You cant make money without spending any aside from doing all the dev yourself which you have no apparent interest in. however, having everything documented very detailed will ensure that you get something you can build on top of if you decide to outsource anything.
