small keygen script

I am looking for an experienced PHP-coder who knows how to write fast and secure code. I need one page where the user can enter his name, e-mail-address and a unique ID. After doing so he will receive a serial/license for unlocking/activating a software application. The unique ID will be taken from a flash-game, which displays this uniquely generated ID at the end of the last level. In other words: the user plays a flash-game. If he wins, he will get the unique ID displayed plus the URL of the formular where he can enter name/e-mail/unique ID. It is important that every user can generate only one serial. Means, we need to either check for unique IDs which are duplicate, or maybe also duplicate e-mail-addresses. However, I am open for suggestions here, that's why I need someone who can propose some nice and easy system for this which is secure and guarantees that every unique ID is used only once/for one user. There should be a small page for the admin where he can see how many users were registered/entered a unique ID for getting a free serial/license. The script for generating the serials is ready, it is a small php-file which I will provide you with of course. ## 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.
