Create CNC software

I work with a company based out of China. We are looking for new software to run our CNC machines. We are looking for someone who is able to review the current software we are using, and come up with a program that implements the changes we want, and keep all the functions of the old software, and be compatible with our control cards. The current software has been discontinued by the company that makes the control cards, however they continue to make the control cards. The program will also need to have hardware security, aka a security dongle. When you are done we want our company to own the software and the intellectual rights to it. If you live in the Atlanta area I have one of the CNC machines set up you can see what our needs are in person. But I'm willing to work with someone who can only telecommute. Contact me for any more information and any inquiries.
