2. do a 'partial commission'. by this i mean that you are not demanding full exclusive rights to the final product, and afterwards the vendor can put it in their own store and sell it. so you are paying a fee to basically 'hijack' a vendor's direction. 

 

This wouldn't be a bad idea at all, and I suspect that the folks stumping the initial cash wouldn't mind or care either way if it got sold commercially afterwards.
