Zen-Cart Customization - Add Revenue to URL as a parameter on the Checkout Success Page

I need a customization written for a Zen-Cart 1.3.7 store. Zen-Cart is an open source shopping cart written in PHP. I would like to have a URL parameter added to the Checkout Success page (after payment has been accepted). I would like the order revenue, shipping, and sales tax added to the URL as a URL parameter (i.e. [login to view URL]) Ideally this will not modify any core files of Zen-Cart or the modifications will be stand-alone via an include file so the customization can be easily moved over during a future upgrade. ## Deliverables 1) Complete and fully-functional working program(s) in PHP/text based files as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows: a) PHP and/or other text based files with instructions on how to install in my store. It is fair to assume that I am running a default installation of Zen-Cart 1.3.7 as can be downloaded from Sourceforge with the exception of the additional "SEO URL's" module mentioned in the platform section of this request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform I am using Zen Cart 1.3.7 with the [login to view URL] (AIM), PayPal Express Checkout, and Google Checkout modules installed/enabled for payment. We utilize the built-in UPS shipping module for shipping price calculations. We also have installed a custom module called "SEO URL's" that can be downloaded from the Zen-Cart home page under "Downloads." This customization should work with all 3 payment options, the UPS shipping option and take into account the SEO URL's module which changes the checkout success URL to [login to view URL]
