Have you looked into a CSA (community supported agriculture)? I don't live anywhere near Texas, but they are pretty common up here in the northeast. You essentially share the risk/benefit with a local farm. At the beginning of the season you commit to a certain size box of vegetables that you either pick up or is delivered to you each week. They vary a lot as far as conventional to organic produce, vegetable selection, fruits, some even do meat or dairy, it just depends on the farm. Some also allow you to work hours on the farm in exchange for a portion of your share. If you are interested go to localharvest.org and search in your area. Email a few farms or visit their websites and figure out how much you will have to spend and how much you can get. For about $28 per week this summer we got 10-12 items in our box each week, more than enough for a vegetarian family of 3 and all of it was organic.
