Hello,
I have 17 years of experience in development, highly skilled in C++ and C#.NET. Since I'm new here and want to build a reputation, I will charge only NZD 7.00 /h, but I guarantee a top quality job.
I will need to see the code so I can analyze how much time it will take, then I can give you a precise cost and schedule, or I can use Freelancer Desktop App if you prefer.
Best regards,
Arthur Lopes
