Take the money and book a hunt somewhere. Dude, my back yard is three acres. You are not going to create a deer haven.
2) find someone to plant your one acre for you. I'd suggest asking around either at the seed store or at the archery shop. Lots of like minded guys there.
3) probably need to spray this week. I wouldn't risk waiting. Tractor Supply has Gly....60$. Harbor Frieght has a 4 gallon backpack sprayer for 40$. Maybe a couple of dollars for some dye since you'll spray manually. You'll finish an acre in an hour or two . That'll give you 10 days to line up someone to till and plant. Good luck and happy hunting
You're going to need to get the ground rototilled or disced. Try to find someone in the area with a tractor and some attachments.
Winter rye 100#'s per acre (Not ryegrass seed) Red Clover 6#'s per acre and White clover at 3#'s per acre for diversity
Weeds will be dying, but you should scuff up the dirt for better seed to soil contact. Broadcast the rye grain first, then smooth if you can. Then broadcast the clovers and smooth again. A couple weeks after germination, you could broadcast some more rye into the field as it will stay green later (it is younger) than the first seeding. All should green up in the spring. Rye has a great root system for organic matter and clovers fixated nitrogen.
After the threat of frost is gone next year, 50# buckwheat per acre. Grows fast, prevents weeds, good soil builder and is killed easily if the deer don't obliterate it, by mowing or dragging. Then you can get ready for next fall. Good luck.
