You can work with St. Barbara as St. Barbara without needing to look into the religion.
Here's a good site though:http://santeriachurch.org/
Dr. E, bless his soul, has contributed a great deal to the community. Especially with SAFE.
I also believe Masego and Hastv on this site know a great deal about Santeria, and they may know a few people willing to help. Maybe shoot them a mail?
