Artist / Music / Entertainment Website Design

I am requesting quotes to build a music artist / fan / entertainment website. Site must be of a modern design utilizing minimal flash elements. Must employ a design and programming that employs search engine optimization. The site must have customizable artist pages (5-10) with twitter and Facebook integration. Fans must be able to comment / follow the artist's twitter / Facebook chats via the page. YouTube integration must also be included. Ustream capability must be incorporated via a live stream area. Must include a music area for download and linkage to the artist's iTunes store. Site must also have a photo gallery that allows user comments. The site must be customizable. Must also have a mobile formatted version that auto-directs when visited via mobile device. Example of artist site with similar functionality is 50cent.com.
