payment processor integration

We are a small distributor of various payment processing services to commercial clients. We recently developed a proprietary POS device and are currently in the processing of integration this service with a small handful of processors and banks. This particular service runs on a Verifone VX520. I am searching for someone who can implement transaction specification provided by the various processors and operate in a sandbox environment until successful test transactions are achieved.

Thank you
