If you dont have the equipment(atleast a 35hp tractor, harrow, and a spreader), a pile of corn works good for hunting season. There is not a way I know of to get started on the cheap. Can you borrow the equipment from someone?

Wait, what about honeysuckle's around the borders and apple tree's, persimmon, or honey locust, even white oaks if you are patient? You can probably get a decent stand of clover pretty easy with a rake and arainy start(hard to come by in NC). IMO if you want easy and cheap you had better work with what the good lord wants there(native browse).
