Considering the actual cost of doing business, an electrician could not manage payroll, insurance, and continual education on that wage. Even if the electrician was just desperate for any source of income, including the less than minimum wage that job would actually pay. It's illegal in many jurisdictions, and serious bankruptcy ensuring NFPA 70e violation in others. Granted, there are some ways around that... but it would hardly be worth it in the above mentioned case. As for being asked to make a firm bid, sight unseen, on such an old house... even if it wasn't averaged down to $12 an hour... any electrician who bid that job would be insane. There are variables that could add thousands to the costs that could only be discovered by scoping it out.
You are correct though, that if the person just showed up as a consultant they could avoid a lot of the drama. Granted than they couldn't pull the permit, physically touch anything, and certainly not bid on the job as requested.
Wait, wait, wait! The electrician is not bringin' his crew, and from my interpretation, nothin' more than his expertise. The home owner is acting as the contractor, which as far as I know, is legal in all 50 states! You can do your own work on your house without havin' to be licensed with the state. Sounds like he's just wantin' a guy to guide him thru it. At least that's the way I've done it in the past. Bein' as he's talkin' 12/hr, it couldn't be anything else!
I could be wrong, but this sort of thing is gettin' pretty popular around here. I helped a guy build a lake cabin a few years back, he paid me 16/hr to make sure he didn't **** it up and to help get him thru the building inspections. The guy didn't know his ass from a hole in the ground, but was handy with his tools. Turned out pretty damn nice! Most of the time I didn't do much more than drink his beer. Him, his kids and friends did the work. They just needed to know how.
Givin' 'em a bid in this instance is estimating what it will cost the home owner in material, permits, etc. The reason I say this is, when you put in a bid, there's no hourly wage involved. It's included in the bid.
