Follow Jockeys advice on this topic. I know a handful of electricians. Yes, they do keep busy. Stringing wire in old buildings, crawlspaces and attics when it's 90 degrees outside and 120 degrees where they're crawling amidst the fiberglass insulation, cobwebs and filth isn't one of the favorite parts of their job they tell me. It is good honest and necessary work though.
