Verifone vx810 offline

I need someone that has prior experience in Verifone Vx POS Software Development. I need a Verifone vx810 offline software that will log: t1+t2+pin and print out receipt saying either: Approved or Communication Error. Further customization is needed. Need to have the offline software to look and function like a REAL Verifone vx810 that i have. I can ship you the terminal that you can use to create an identical offline software for. So it will look the same as real one, but only function as t1+t2+pin logger. Thanks!
