I help by baling straw, hay, and giving away veggies grown in the garden in such. I know one guy who gives watermelons to all of the people with whom's land he hunts on. If she doesn't need your help, help out someone she knows and maybe you could get a good recommendation. It worked for me. Now 6 surrounding neighbors allow me to hunt on their land. I also now have over 546 total acres I hunt by myself. She might give in sometime.
