I think you may have missed the point.
No, they didn't get a permit. Are you saying a permit is required even if an electrician replaces an outlet or light switch, or does any other small amount of repair work in a private residence?
This was the first and only electrical contractor I called. And, yes, I was glad they answered the phone when I called, glad the owner understood what I needed to have done, and glad they said they could send someone out that day or the next morning at the latest even though it wasn't an emergency or rush job. When the kid arrived to do the work at 3:30 PM, he said it would take at least 2 or 3 hours, so he couldn't do it that day because he would be there until 6 PM. Instead, he said he'll write up a work order and come back and do it the next day. All of that took 20 or 25 minutes. The job itself took him just under 40 minutes -- start to finish. So, my thinking was simply that I thought he was coming out to do the work on the first day and if he had done it when he showed up as expected it would have taken him from 3:30 to somewhere between 4:10 and 4:30. If he then said the cost was $200 plus materials (22 feet of 220 wire), say $225, I would have thought that was fine. It would have meant that he showed up, he did the work, his charge was reasonable enough, and I could count on calling the same company again and again.
As far as, "Be happy you found someone just to give you a price, let alone come out and do the job", I was glad about that part, but I don't think I should feel thrilled about it simply because there is an electrical contractor out there who is willing to do a small job for a homeowner. Maybe we should make it easier in New Jersey for people to become licensed electricians. Then there would be more of them and I wouldn't have to feel so privileged that a licensed electrician was willing to give me a price and do a job. Maybe there should be 3 types of electrician licenses -- a licensed residential electrician (Level 1), a licensed commercial and residential electrician (Level 2), and a licensed electrical contractor (Level 3).
