52285 Category Affiliate Listing

What I need is a scaleable backend to run a system very similiar to a hosting directory. However, instead of individual companies submitting their host, it would be only me putting in entries for offers (from affiliate programs). It should have a modifyable category system that lists offers, as well as things like featured offers, new, limited, mail a friend, and others. The site this will be installed on is www.fsindex.com. I shoul be abple to put in an offer, in which I'd include: a name, a description, an affiliate link, category, and image, as well as an ending date (I should also be able to choose 'never'). The script would then enter in the offer into the proper category, make a listing int he category page (which would include links directly to the offer, or to the landing page where more information would be displayed). When someone clicks on an offer, the script should track the click and show a hit counter for each in the admin control panel. An optional addon would be tracking the user from the beginning and seeing where they come from, and where they go (offerwise). Should include an easy-to-use admin control panel where entries cna be added/removed/edited easily, and stats shown, as well as a few other things you can think of. Should also be easy to skin. I want to be able to make a few different sites with this, each with different designs. PHP should be ogranized well, and easily modifyable. I will be the sole owner.
