PSI Gate payment mod

I’m looking for a payment mod for the PSI Gate gateway. There is a fellow (Steve Rio) who posted that he had done this and offered for sale on this forum, but he has not responded to my requests for a price on his mod.

Does anyone else have a source besides the CS-Cart custom development team for this? I don’t mind paying for it, but there development time is 2 weeks before they can start. Any direction would be appreciated.
