We had a very high air radon level, so we had the radon mitigation guy come in to install a system in the basement. Chatting with him after, he says that his business has some breakpoints for size. You work for yourself, with one helper, or you can have a number crews of a couple guys each that you supervise. He wanted to be the latter, but he has had such trouble at his size, with the single assistant, that he's now wondering if it's worth going big. The assistants he has had have either been teenagers, with "constant dram texting with their girlfriend" all day, or they are older guys with some DUI's who need rides to get places and are unreliably there, or have bad attitudes. He figures if he goes big he's just going to have more of that headache.
He says he doesn't pay badly, and it's a trade that can be learned pretty quickly if people wanted to work for him for a year and then go out on their own, but people don't want to wait that long. It can't pay that badly. I paid him $1100 for a few hours work, and I don't think the fans and gauges are that expensive. The concrete drilling and PVC pipe can't cost that much. I'm paying for his knowledge and skill. When the economy is this good, it's hard to find good workers for some jobs, so you have to take what's there.
I told him I'd keep an eye out for a good worker who might want to come his way.
