You don't need a lot of land that is for sure. I know the interest is there because we quickly got 13 members to join... I think it took 3 days after advertising, which is awesome. As far as space requirements it's 50x150 for our vegetable garden and we have 75 blueberry plants and 2,000 strawberry plants not sure on the size of those.
See I feel the opposite, I believe you would make more money from the CSA than from taking your produce to market every week. We are going to do both this year to see how it works out but last year the market was hit and miss. If it would rain it would really slow down our sales for the day on the produce. Once you pick it, fresh produce doesn't stay good for very long. It was almost like giving our garden away. This way we have money up front, for instance we only require a down payment and then weekly from there. However the option to pay all at once or monthly is ok to, as long as we get an initial down payment and money on a regular basis I don't really care how they pay. However having a couple members already pay up front was great because I just bought shelves, lights, seeds, hooks, chains, greenhouse, ect and the total was well over $2,000 for everything.... which is now paid for by the CSA members.
The first year is tough because of all of the new things you have to buy but I'm so used to it that it's not a big deal to budget for buying supplies and equipment. I can't wait until the day that I don't have to make huge investments and can enjoy my profits! But even then you have repairs, replacements, and so on.
I think the CSA is the way to go so far. From my experience just from a few weeks is to stay on top of your game, be organized, be personable, and keep up communication.
Thanks for all the comments I appreciate it...
