PPC Affiliate Marketing Tracking Script in PHP

I need a php program which will track performance of a PPC advertising campaign. This program will monitor conversions from.. 1 - the keyword bid on, to... 2 - the ad which was clicked, then to... 3 - the landing page on my site that the user lands on. Tracking variables for each of these 3 steps are recorded and then entered into a subid parameter in the affiliate offer URL. This way I can monitor exactly which keyword, ad, and landing page was responsible for each sale. I will also need this integrated with a simple split testing script I can use to test different landing pages. I know a bit of php, but don't have time to program this myself. However, I have much of the pseudo-code worked out, as well as some parts of the actual code. But I need someone to put it all together. I need an experienced php programmer capable of writing clean and secure code, with decent code documentation. Preferably someone who has written a similar script before and/or understands online conversion tracking, particularly from an affiliate marketing perspective. If this looks like the project for you, I can send much more detailed instructions. ## 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.
