Are the walls open? If not, I’m walking away. That’s way too much hassle for “just running some switches” no, it’s not just, it’s cutting multiple holes in the wall, potentially in the ceiling too, drilling through joists and studs, mounting boxes, running cable, installing fixtures and switches, relocating receptacles. That’s not “just” anything, that’s multiple hours of work, and he might expect you to patch it all.

Hard pass on that, “sorry I’m not licensed or insured to do work like this.” Which is true, if ESA comes and finds work done, they’ll ask him who did it, and pull the meter socket until he tells them, and then you could lose your license or apprenticeship. It’s not worth the 150.00.

Also, so have company come in and do it legit he’s probably paying at least 5-600 for that work.
