I have looked at this for years. You really need to be near a high income area to make it work. I have been to the A2 farmers market, and have spoken to vendors coming from Ohio and Indiana, plus folks from 2 hours+ drive in Michigan, they go to the A2 market. It is the best money for them, they will travel a couple of hours each way to peddle there. There is a waiting list to get into the market, and pretty strict requirements ( mostly very little reselling ). To me, the production would be interesting, the marketing would be a lot of long hours in Michigan weather, lots of driving, for not a whole lot of money. My dad and both grandparents did truck farming, there aren't many doing that now - it's hard work for low pay. I suspect some of these folks aren't even making minimum wage, after all the costs are accounted for. I talked to one guy at a local market that was trying to save $300 to buy a small greenhouse to start plants in. I think he gave up, I never saw him again. And the 3 acres of strawberries that my dad did were a lot of hard stoop labor. High value crops usually means high labor inputs. And crops need work at certain times - you simply can't put things off, You need to pull some long, hard days sometimes.
Basically if it was easy, everybody with a couple of acres would be producing something.
