Why do you need Bahun? Forget about the caste. There are so many other caste people in Sansrkit University in Nepal. You better call it "BAHUN", instead call it pandit, or pujari or something that closely resembles. There are so many bahuns in Jersey areas but they can not perform ritual stuffs but if you you call a pandit, perhaps s/he can perofrm it.

Good luck on your finding ...
