random idea: why not open a hostel/retreat for programmers to come work on your farm for weeklong increments. Free room/board in exchange for 8hrs labor. Post videos of exactly what kind of work is awaiting them, and interviews of people who have tried it. You get free labor on your farm, and a passive "income" source, they get to step away from their burned-out, fluorescent-lit cubicles and actually get to try living as a farmer. A lot of people have this fantasy, so I suspect there would be a good-size market of people who would love to try it.
