What I need is someone who is thoroughly familiar with Magento payment methods. On this project, we are not using any standard methods. We are making a new one. However, the concept itself is not complicated. It is similar to PayPal, in that we are simply sending over a few variables, letting that system handle the payment, and then, once the payment is complete, I can have that system return whatever is needed by Magento to confirm payment.
It may be even more simple that paypal, because we only need to send over a few arguments such as customer name, email address, the amount, and something to track the specific order by, such as an order number. I have specific arguments I need passed, and I can return whatever is needed from the payment portal.
If Magento must pass additional information, that is fine. For instance, the return URLs are something that is passed into Paypal. I actually hope to simplify how much information is passed between the two.
We intend on passing a security key as well, and I have method we have used here before that works well for this.
So the job is to create a new payment method in Magento, pass me some arguments, and accept the return arguments so that you may confirm or otherwise set the status of the order.
