audio file compiler

I'd like a web-based application that does the following. Allows a user to sign up, choose password, and edit a small profile. Allow users to upload audio files, and then have other users play the files and post comments about the uploaded audio files. Until a certain percentage of users have commented on the file, the comments would not be available to the remaining users. I'd also need to have certain users or moderators be able to view diagnostics, i.e. when users last posted, how many times they've posted comments, what percentage of files they've commented on since joining. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
