CD Baby - User Generated Content Music Distribution Website

I currently have a Joomla website with Jomsocial User profiles. I need to integrate the ability for my users to upload their music, generate RSS, and sell their music on my website. I would like to use the jomsocial groups as the sales page and rename the groups "fan pages." The user will need to be able to connect their sells account to their paypal or money bookers account. Also, the page used to download the music should have a clean look. Similar websites are CD Baby and reverbnation. If, you have done similar projects please post the links or your portfolio. Please advise if you are also able to make an embedded player that the user can post to his own website or blog and what your separate bid would be if I include this in the job.
