I found this lady while looking through "American Indian Groups" of Facebook. She has a sweat lodge group there and a link to her website. http://www.facebook.com/group.php?sid=aecca79b04f512be5f7f381ac50dfd6f&gid=21467398322
On her website is a page with the cost of a "Full Moon Native American Indian Sweat Lodge & Reiki"- $30 a person.
