non-profit association

I'm a karate orphan. Although I used to belong to a major karate organization, my most senior teachers and I are all independent. I am going to start teaching a karate class at a local rec center and would like to have some form of affiliation though for my students and my own professional development. Can anyone recommend an association that might help me out with identifying and association that meets the following criteria:

supports traditional karate
is open to new members
will recognize my rank/experience (nidan/20+ years in MA)
will recognize my students
operates as a non-profit
offers training and support for members

I do not need:

insurance (covered by the rec department)
competition ranking

thanks,
geoff
