There is a subforum in the gallery, but I don't know of a list. I think a lot of them don't want or need to be on a list.
Every once in a while I see someone post a cue they made, and I have seen that person post for some time but never knew they made cues. Every once in a while I am stunned by what such a person has made. They make cues for themselves, friends, etc. No list to get on. No formal orders. And it seems that's the way they like it.
And then there are those that are not on AZB...believe it or not.
Occasionally I see one that I never heard of before that builds amazing cues, has done so for a number of years, and others know about him.
If there is a list I don't know about it. And I doubt it would ever be complete anyway.
