T-shirt design - How to Profit

If I had a T-shirt design that I thought would be great to sell, and giving that many online retailers take ideas, what would the best place to submit my idea to and profit? Can I give my idea to more than one store, or is that "illegal"? I have a pretty funny idea in mind, so any help is appreciated! Thanks!

I used to have free access to a silkscreen machine so long ago that I forgot how to use one. But I did easily design and make a few shirts. So simply, design and make product, advertise, sell! Put a (C) on it with your brand/name before the year rolls over.
