Coremedia CMS Project

We need a Programmer with experience in the coremedia CMS Sotware. We want to implement a subscription manager. A User can subscribe online with a username and Email Address. He also has to check which Articles he wants to subscribe to. The data must be stored in an oracle database. The subscription system then must send the relevant Articles (PDFs on the filesystem or in the database) to the appropriate User via Email. User must also have the chance to unsubscribe from the system. All the needed JSPs, servlets, etc. must be implemented in the coremedia infrastructure. For Example the list of the available Articles must be maintained through an editor, so one Article must be some kind of "document type" in coremedia terminology with an external link to the PDF. There should also be statistics on e.g. how many users subscribetd to which Articles. The system should be open enough to replace the email channel with RSS.
