Looking for a native American teacher

We are looking for a native American teacher to help us improve our English speaking skills, especially help us improve our local accents, pronunciation, correct intonation, etc. There will be 2-3 people to attend the class that is more preferable on weekend.
Thank you,

Hau! (how) not many Native Americans left I am afraid 96% died in the 17th century from small pox and measles (they had no immunity).

Joking and history lesson apart why American?
