I have no idea what buying and selling land is like in the USA so this could be way off target but....
For quick(ish) money, could you not divide the land into a few smaller parcels and sell some off for people to build on, small lots, like the ones surrounding the larger plot.
On the agricultural land, presumably you can build your house there if you class it as a farmhouse, perhaps a fishing pond would earn you some money - easy stuff so parents can bring their children to learn fishing. Keep some of the trees for a nice natural setting. Just a thought...
Looks like a nice place to be, good luck on selling
