Enhancements for new Social Networking site

We are in the final stage of developing a Social Networking site for music artist and music fans. The site will be launched soon but prior to that we would need some additional fuctionality in the site. In the attachments you will find a description of the requirements. We are looking for a partner who can complete this functionality within a short time frame. If this is done satisfactorily we will also work with this partner in future enhancements for the site which will be continuously evolving. We are looking for a partner with proven skills to complete the project succesfully. Bidders should present relevant examples of previous projects they have completed, which prove their skills.
