Hello John,
I would try to get in touch with an organization that has a land matching program. These programs are designed to match farmers/land owners with those who wish to lease land. Where I am from in SE PA - I know at one point in time the French & Pickering Creeks Conservation Trust had a program like this before I moved to Colorado. I would contact them and see if it still exists. Northern Chester County is a beautiful area that can severely use farmers in order to keep developers at bay and preserve the historic rural character of the area. People in that area are very much into patronizing
sustainable agriculture operations as well!
Good Luck in your search
