I would consider myself a great candidate for this project as I have worked with FoxPro since it was FoxBase back in 1987 before being bought out by Microsoft. I have worked with VFP since version 3 was released in the early 90's and work with it today still. I have a wide variety of experience in many different business applications and was an accounting specialist with VFP applications through the entire 90's and early 2000's.
I can do this type of job at a low-cost as I just enjoy offering my time for projects like this. You ask for a conversion to VFP so it can run on Windows 64-bit, but that should not actually be any issue. Why? VFP is only a 32-bit architecture even IF run on 64-bit machine. If you want to convert FROM VFP to a 64-bit platform, such as I would do C#.net, I could do that too, but VFP's engine is so fast and easy to work with. VFP itself will never run AS as a 64-bit application, just 32, even on a Windows 64-bit machine without any issue.
Let me know if you have any questions about this. Payment would only be payable when the conversion would be complete AND accepted. If it doesn't work out, you pay nothing, no risk to you.
If a conversion to a 64-bit platform, no problem either, but clarification of the amount of work your current application DOES have integrated is really way too short a description to truly know how much time a project would take to complete.
