Wow. Wow wow wow lol
a couple of these suggestions are just wow! Talk about screwing over you or the next guy if you ever sell!
I’ll say that here in eastern Washington, $2,000 would get you a trench, conduit between the panels depending on location and IF they’re up to code already, and wire pulled between boxes.
If a licensed electrician touches preexisting electrical, we have to, by code, bring it up to current code spec. If you had a quote for time, materials and permit pulls, for $2,xxx 😍 I would consider you crazy for not taking that deal! By all means, if you had a friend, or if I came through town I would absolutely help to make it cheaper. But man o man that’s a damn DAMN good price for the little you need.
Look over your quote and make sure that it doesn’t say “upon further inspection” or “pending code issues” or something like that. If it’s a guaranteed job done at that cost, IF they run into code issues, it’s on them because they didn’t quote it right.
