Ok, here's the deal.
We need a programmer to write a contribution to osCommerce (open source shopping cart) to enable support of our payment gateway ([url removed, login to view]).
Obviously, we have made such support possible from our side. We will provide trial account access and explain how our gateway works to the winning professional. Actually, there will be not much to explain, everything is consicely documented.
As we see it, we need a professional familiar with osCommerce cart, or willing to learn the necessary parts of it.
In the end, we would like to see complete integration, where the osCommerce user only needs to input the Vendor account ID and validation word in the osCommerce panel for all transactions to start working. Names, descriptions and prices of products in the cart will have to be automatically POSTed to our server every transaction. All technical info from our side will be concisely provided.
