Having spent a great deal of time on Cheyenne River and Rosebud (two other Lakota Reservations in SD) I suggest that if you can't do what Mr. Yenne recommended that you abandon the project altogether. You're not going to capture the "essence" of anything talking to people who are removed from the place - and place is vitally important to the Lakota. To truly capture the voices you're looking for could take years. I'm a bit disappointed that SOF would fail to "get it right" because there are no guarantees of "finding the voices" you need.
