I want to create a site with many pay per view options.

Hi, I want to create a site with many pay per view options. Such views shall be shortlinks that I can manage in terms of duration for their validity / expiry, promotional purposes (change pricing for the same underlying link) and integrate payment of such links via paypal. I have tried marketplace and payperview and the link management seems a little weak for what I want to do. Any idea or recommendation for someone who can help program my needs?
Thanks
Christoph
