If you want to use your hands and collaborate with humans a lot in person, the trades seem to be quite exciting right now. Salaries are also good — A good plumber in our area makes nearly $800/hr, and that's not touching what the datacenter plumbing folks are making.
With 10 yrs experience and taking travel jobs to remote locations you MIGHT break $100 hr without OT. With North Slope experience you can get jobs that are paying ~70 with guaranteed OT so like you will crack $100 /hr but that's working winter in Alaska. Even offshore jobs aren't paying $100. No one is paying 800.
The more important question is: How many hours?
My side gig pays around that, but there aren't many hours involved it in, and there isn't a good opportunity to find more hours, so it isn't all that much money at the end of the year. It is a tidy job for the effort required, but you wouldn't want to have to live off its income.
Not a typo. The good plumbers bill by $180-200 per 15 minutes. If they are independent, they take all of that home. If they are part of a larger company, they are still pocketing a significant portion of that billing depending on how the plumbing company operates.
Plumber makes $800/hr, or bills you are $800/hr?
That's still quite good either way, but OP should understand that even in most expensive US cities a journeyman plumber is typically pulling at most like $150k-$200k without doing significant overtime. And you won't get there until 5++ years on the job.
So think more like $100/hr of actual compensation on the higher end.
Not a bad gig at all. But that $800 number comes with a lot of caveats.
