I believe something like the Zazzle store or cafepress, you make a design and upload it. Set up a store, and when someone orders it comes from wherever they are made, to the person who ordered, and Rich would get a cut.
If we had any members with some design talent, we could do a little drive to pick some designs. The set up on those is pretty easy, it doesn't require work really after its set up, and you don't have to manage the orders from what I understand. Might be worth looking into.
