I use to use Network 1 (EFTSecure, https://va.eftsecure.net), they were really easy to interface with using perl. Basically, we would open a secure pipe, send them the info and listen for the error code. They had a script that almost worked, but with a few hacks you could be up in going in 5-10 minutes. They had other hang-ups though, like declining orders if they were too far above you average sale price. But for a subscription service, this should not be a problem.
