BuddyPress eCommerce Plugin

Please read this description of what I need. As many people do not read it, then quote me higher. I am working with the Kleo Theme (Link Below) for wordpress. My site is a stock footage site. I want a ecommerce widget that uses BuddyPress so that when members upload footage it can be attached to there profile. If this cant be done, this is fine as long as peoples uploads are connected to there profile. My site is a membership site, which I have the membership plugin, but people will be charged for downloads only using credits. This is simple. When someone uploads a video, the receive 5 credits, when the download a credit they will spend 1 credit. We need our own player (not youtube or vimeo) with a option to add a watermark. Here are the bullet points to some it up: *Multi-Vendor Marketplace with forms to fill out for videos *Credits based website (no currency) *People are not selling there videos, so there shouldnt be a pricing option for the vendors *Video are shown on the profile of whoever uploaded it. *Videos will also be shown on a main page, with search functions provided by the form that they fill out. *Backend approval for videos needed Please let me know if you have any questions.
