Unless you’re absolutely set on October, see Dukxdog’s thread about “good hunting this year in SD” a little below yours. He’s has what you are looking for but is filled until December.
Let me say a word about December — it’s when our group goes and while we’ve hit a snow storm or two the hunting has been very good; admittedly you are playing some weather-roulette, but the non-res crowds are gone and there will still be plenty of birds available.
