Client is using Redfin as their Payment Gateway? Is there any way to make MarketPress work?

Hello.

My client is using a Payment Gateway that is not one of the 15 that you have listed. They are using Redfin. Is there a way to make it work with Marketpress without too much coding? There is a plug-in made by Pledged Plugins that uses Woocommerce. Do you have anything like that to work with MarketPress?
