I have a whole folder on my machine with tons of resources for Chatino, several papers (some in Spanish, most in English), comments on some of those papers, and at least four dictionaries and a few wordlists for more than one variety. It also has some tangentially related stuff, like a list of indigenous languages in Mexico and how many villages within a certain area speak each one. I'm not sure how to share it with anyone who's interested, though.
I guess I'd just have to make it a .tar.gz file?
I don't speak Chatino or anything, but I might be able to help!
