SD runs a lottery for their non resident waterfowl licenses. The draw was in july. There are some left over licenses for private land only along the missouri river...mainly those are used by clients of guides targeting late season geese. Could be an option for you.
Otherwise, load up 4 dozen goose silhouettes, 3 mojos, a few layout blinds, a dozen duck floaters and some binoculars and drive to ND and freelance. No guide needed.
