Need a custom distribution module

I need a digital distribution module made custom for my website. Mod should perform like tunecore.com; cdbaby.com; and mondotunes.com. Module should be able to allow artist to distribute their music and collect royalty payments for it. I have other examples and more information if developer contacts me back. Please only contact me if you have a good knowledge about how to create modules dealing with music, distribution, payments, ect.
