If you could get the machinery up there you might look at something like a swale system with some fast growing pioneer species planted heavily into the down slope berms. I'm thinking some things like locust, seaberry, clover, the nettle you already have, etc. I wouldn't expect to get much of a harvest until you build up the soil with those pioneers (seaberry will get you something though). If you can integrate some type of livestock into the system you should increase fertility exponentially if properly managed (sheep, chickens, geese, and ducks are all pretty easy to manage, and cattle if you can swing it would be pretty nice). You could start chop and dropping that nettle now to increase organic matter quickly. It sounds like you have a pretty rough piece of land there... perfect canvas for a permaculture masterpiece! Don't give up!
