I have decided to use Xoops as my CMS, and want to use Zen Cart as the shopping cart. However, I use PayPal Website Payments Pro as my credit card processor. However, the Xoops module available to integrate Zen Cart is Zen Cart [url removed, login to view], which does not include the payment gateway to PayPal Website Payments Pro. Zen Cart Version 1.3.8 includes the payment gateway for PayPal Website Payments Pro, but is not yet available as a Xoops module.
My first preference would be to have the Zen Cart Version 1.3.8 converted to a Xoops module so that I can simply install it myself, etc. However, this may be cost prohibitive, so my second preference would be to add the PayPal Website Payments Pro gateway to the Zen Cart [url removed, login to view] Xoops module. Hopefully, you could do this so that I can simply install this module, etc. If not, I may need you to install the payment gateway script on my host.
Please detail your exact approach for this solution with your bid.
