Paid work for LUA script programmer to write script for limit switch to sense winch servo unwind

I need a LUA script programmer to develop a scrip that will see if a limit switch is NO or NC to control the unwinding of a Servo Winch. when limit switch is NO = stop unwinding. if limit switch is NC allow unwinding (or reverse depending on best practice). at any stage I can change the toggel to wind up winch… all this is activated by a toggel switch on controller (manual only - no need for auto/mission control at this point). I will also need the programmer to advise on hardware wiring and mission planner settings.
Please contact me if you are interested. Sorry in advance if I have broken any forum rules. This is a commercial venture so happy to pay commercial rates. Need it completed and operational by end of October this year.
Kind Regards
