I second the suggestion for seedlings from the state dept of whatever. I've put in 150 nut, fruit, firewood and N fixer seedlings this spring, at ~$.50 each, including shipping.
Check your state for help. I do not know of any programs to help you buy land, but my state has lots programs to help farmers. Unfortunately, they all require 5+ acres to participate, and I only have 3.
If you can get a larger parcel than you need to support yourself, perhaps because some of it is marginal (eg rocky, too steep, inaccessible), look for programs which pay you not to use it. Like native grasses, not logging your woods or not starting a dairy farm.
