Controller interfacing a retrofit job

I have two CNC KIRLOSKAR EC410 Lathe machines. They are fitted with 1990s controllers , outdated now. I wish to change them and fit them with another present day controller. We need a technician who understands the voltages, does basic electrical, mechanical debugging and can do wiring where ever needed. He should know what is an encoder, limit switch, relay, fuses, transformer, rectifier and should be able to solder connectors .
