Verotel Integration

I'm looking for someone to integrate Verotel's payment system into several adult online fetish communities. Verotel has been used on the sites before for direct debit transactions. We need to add credit card support as a backup provider to our primary processor CCBill. Verotel doesn't offer a php script so I'm looking for someone who is familiar with Verotel's products who has some experience working with the support staff at Verotel.
