Add MasterCard's MiGS (Mastercard Internet Gateway Service) into Convergine's BookingWizz Credit Card Payments modules.

I bought Convergine BookingWizz 5.4 Booking system and add-on BookingWizz Credit Card Payments v2.1 modules. The Credit Card Payment modules already integrated with several most popular payment gateways such as PayPal PRO, Moneris US, Moneris CA, OptimalPayments, InternetSecure, Elavon, [login to view URL], eWay, PaymentExpress, Stripe, FirstData (linkpoint). WHAT I NEED is to add another payment gateways which is most bank’s native gateway system - MasterCard MiGS (Mastercard Internet Gateway Service) to be included into the payment gateways list. FTP account for u to access my website related folder will be given, and the php script's core system & addon will be provided once I'm interested with your price. My budget is very limited, it's just such a small add-on. I need this ASAP, I am looking forward about your custom development inquiry and will reply as soon as possible.
