Plumber and electricians are usually employable and paid well, so long the city has that setup. It really depends on the type of place you live though. Higher income city? Landscaper/groundskeeper or house cleaner are good options, people are willing to pay to not need to do normal house chores. Many farms nearby? Livestock vet or slaughter/butcher. Lots of tech? Software/electrical/mechanical engineer, city depending. Someone mentioned teacher but I'd say look at salary first. Location depending, many are not paid well and the job can require up to 70 hours/week, which can be less than minimum wage of the same location. They also mentioned nursing, which is pretty good, but may require long hours depending on where you work.
