Blog with user uploader feature for multimedia

Multi-Media blog - for users to upload own multimedia. I need a blog-driven website developed that has the functionality for the end users to upload thier own content - music, pictures, video, etc. with standard blog text areas that can be posted next to the image. I am calling for proposals (doesn't have to be elaborate, just offeriing a proposed solution for this - whether database required, etc), and for estimated work hours and total project price bid. The timeframe on this project is quite urgent, so one would have to be able to commit immediately. Thank you very much.
