I wouldn't wait until spring. He should have no problem once it dries, and that shouldn't take four months! If he won't do it someone else would. I planted alfalfa and ladino clover thisfall and the deer devoured it. I planned on the deer eating some, but they really worked it over good! I am going to wait and see what comes up next spring. I planted two acres, and even got the grazing alfalfa, but they kept it eat down and I didn't get a good germination rate even with good rain. I am thinking about frost seeding some additional alfalfa and clover into a few spots. Good luck.
