My brother does work with bone, antler, silver and turquoise. I could talk to him and see if he would be willing to do something for you... it would most likely have a Native American/southwestern feel to it.

I could also talk to my dad, who is an anthropologist/archaeologist, and specializes in Native American cultures and artifacts, and see if he could come up with an idea for something "traditional" or if he knows someone who does that kind of work...

PM me if interested.
