I checked this out at one point in my area. I found an organic farm that charged something around $150/month (or maybe that was per week) for membership. With membership you were able to go to the farm weekly and pick up a few bags of fresh vegetables and rabbit meat (their specialty) and at times they would have other meat from the few animals they had on the farm. What you get that week depended upon what they harvested that week. It was a pretty decent deal and they gave me a tour of the farm (they charged $10 for tours) to show what types of food they grow and how they grow it. They had some hydroponics, a very good system of raising rabbits and using their droppings to help with fertilization. All quite interesting. In the end, my wife was not up for it. Although she likes meat, she loves animals and if she actually sees the animals that will eventually become meat...she would not be able to eat it. And I am not big on vegetables and that was mainly what they provided so we declined. They actually had a waiting list of people though (since they would only allow for so many people to be members since there is only so much food).
Another local farm I found had organically fed cattle. You could subscribe to that and get a full, half, quarter cattle once every few months. I asked to be put on that waiting list but never heard back.
