I got sound knowledge in C++ and on top toolkits, if you're interested I can write your data mapping algorithm nicely. Please message me to proceed further.
But I need some advance in the begining, but if I am unable to do your project it is my promise that I will refund it. You need make an advance payment for 50%. and remaining 50% after delivery. In mean time if I am unable to do it my promise is there that I will return the full advance payment.
