Kunaki and Amember integration

I need a simple script which automatically processes orders through Kunaki via their XML script ([login to view URL]) Simply, when a customer reaches the [login to view URL] page on my Amember driven site for a certain product (which should be able to be changed by changing a variable declared in the script), the script sends an xml request to Kunaki and orders a product with the name, shipping address, and email from the customer. The credit card number and billing address will always be mine (this also should be able to be changed by changing a variable declared in the script). You may have to use the smarty template page [login to view URL] to accomplish this. It should be very simple for the programmer who is familiar with XML and the Amember script. For someone who is not familiar, it shouldn't be all that hard to figure out. I have a baseline knowledge of PHP, SMARTY, XML, and Amember, so I can help with some of the technical questions if necessary.
