Plumber, carpenter, welder, electrician etc. In the countryside where I live, I do all of these when I feel like it for myself, friends and sometimes strangers in trouble (pipe burst, no power). It pays well; I could live of that and save very comfortably here if I did it half of the time, but I only do it the odd few hours while people begging for welding jobs, wooden doors, etc. It can be a nice little business, especially if you can find employees and move on to house building or renovations, but it will never be bigger than that was of course, you would be in the countryside.
