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.
Honestly, I'd rather hire someone at a reasonable wage, train them, and turn them loose without my supervision, or spend 10k and automate part of my production, than have to supervise people. It's likely a bit different in dairying than it would be for something like vegetable production - I don't have lots of repetitive, low-skill tasks (sorry, vegetable farming people!) like weeding or harvesting that I could safely unleash untrained people upon.
I have a hard enough time finding reliable paid help (and we're well above minimum wage); managing people with even less incentive to put in a day's work isn't that appealing. :)
