When I felt the need to fix up bikes for others, I went to a local organization that went into that line as a part of a social program, and worked on bikes for them. It's a nice thing, especially since the bus company no longer stops on demand, just at stops. This gives disadvantaged persons a means of transport to the bus stop, it gives the social programs another outlet for helping people, and it lets me work on many bicycles without worrying about liability. I also always have somebody do a test ride or two before the bike is given away. That seems the best way to do this anymore. I quit fixing and flipping bikes some years ago because of an increasingly litigious society, and the crap bikes the grocery stores and other outlets sell. Between the two, the game simply was not worth the candle anymore.
