What is the best way to go with a Radio Station? We want ads which a client can purchase, upload a banner and have start showing without our involvement, all from an admin page where they will create an account. Would like to have a header rotating banner, one on each side of the page (beyond a 800 viewport) and a footer rotating banner. We also want employee profiles, a blog, a streaming QT page or ten, and a few recorded video pages etc.
Any ideas it html, php or cgi is better? What is available already that could be converted for use as a radio station? Had looked into just using Auction software, but renaming links accordingly. Unfortunately it limits flexibility. Any help would be most appreciated.
