Many years ago I worked on my neighbors' cars. I did the easy things, rebuilt carburetors, changed points, plugs and wires ,water and fuel pumps, shocks, distributors, alternators/generators,light bulbs and set timing. I never did brakes. I didn't charge, but everyone knew my wife and I liked pizzas so we got several. One owner did give me a soldering gun which I used for several years. I enjoyed it.
