My kitchen has a lighting problem. I need to run 20' of 14/3 from a wall switch to a ceiling light. I will need to replace the switch box and switch. I will need to tie in to a hot in the ceiling light box. I will need to re-configure the wires in another wall switch box so it passes the hot to the ceiling light box. I will then change the light fixture itself. What would all this nominally run if I call a pro?
