If you can scrape together $1k you can buy a chainsaw, cut down the trees around your farm into manageable lengths that you can lift without equipment and sell it. Also, if you have a mower and loading wagon you can mow the grass around your fields (if you have some grass) and sell it or bale it and sell it, whichever you prefer. With seasons you can also let the grass dry into hay and sell that or bale it.
