Helloo there, :)
I'm a U.K engineer who is used to working in telecomms related hardware - a LOT. I've worked for BritishTelecom(landline and broadband routers), and Ericsson in Sweden( Radio Base Stations).
Since the Verifone SDK is in C++ I should be able to help you. (20 years C++ experience, and I also teach C++).
Before I confirm further interest, perhaps you can tell me what exactly this project is about-= and send me a Requirements Specification of some sort, so that I know how much effort is involved...? (and hence, can estimate time and cost)
Thanks
