By all means pay a pro if you cannot do the work.. better than putting 220V across your heart.
But the solution is a valid one. If your mag start on/off switch power is also controlled by the light switch, you turn off the lights, you also deactivate the solenoid control circuit so even if the pressure switch closes it will not energize the compressor motor circuit (the motor circuit will still be hot, just no control signals).
Some conduit, some wire, and wire nuts.
