Flash Widget to Play an Artists Tracks from Web Site

We need to have an Adobe Flash CS4 widget developed that can query artist and track information from our server, display the list of tracks, and when a client clicks on a track in the widget, the track plays. The widget must have a link to jump to the web site URL so the client can license the track. We need the widget to work on MySpace. You can see a functional widget from YouLicense at this URL: [login to view URL] (on the left side, where all the tracks are listed). We need something like that.
