VB and Web Key Gener/PayPal

The project is kinda two-fold for a software program: Scenario 1: A person goes to my site and wants to download the trial and try it out (time based trial). After using it, they decide they want to purchase it, they have the option on the nag screen to buy it and it directs them to my purchase webpage. They pay through PayPal and then receive a registration code after payment is verified (perferrably through email). They enter the registration code in the nag screen which unlocks the software. I want the registration code to be unique to the user so they can't pass the software around. Scenario 2: A person goes to my site and wants to buy the full version. They pay through PayPal and once payment is verified they are directed to a download page (either through email or directly), where they download the software and recieve their registration code (perferrably through email). I don't want the download page to be accessible unless they have paid and are directed to it. I want to prevent the ability of just typing in the URL to the download page. I'm not to concerned about the complexity of the registration key, as long as it is unique to the individual and it is processed automatically. I also would need the payment verification information and customer information stored in a database or automatically sent to me in an email. I already have the website and program, I just need these couple things completed for me. My website is currently hosted through [login to view URL] and I have the Solo XR package in case you need to see what that package allows me to do as far as scripts, etc. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
