When I can find a "day worker" I'll pay $8. an hour for generic work, no power tools, just simple work. If a person can use basic tools, figure out how to do a basic job with only general instructions, $10. an hour.
For a "skilled" day worker who can use power tools, anticipate, take care of tools, safety conscious, put stuff back when finished, then $12. an hour.
I pay my "moonlighting" skilled man $17.50 an hour who can install and repair water lines, sprinklers, do carpentry (wood or metal), has most of own tools, and can do a job with general instructions.
My part-time, occasional, very skilled worker who can weld, run tractor or trencher, install sprinkler lines, do emergency cattle work, etc., $20. an hour.
When I have a turnkey "job" that someone can do, using their own tools, I tell them how much I'll pay for the complete job. If they agree, they do it.
I might add that only rarely do I need someone to do work. Usually only a few hours or 3 or 4 days a year. All of our major work, such as fence building, building construction, etc., is handled by outside contractors.
