looking for sousaphone opportunities in LA

[kontrabass]

I moved to Los Angeles a few months ago to focus on my film scoring and composition career. My touring days are behind me (for now) but I want to keep gigging on a casual level, in any kind of band that could use a sousaphone as a bass. (already done a few banda gigs!)
Anyone have a trad. jazz band in LA that could use an occasional sub, or anything like that?
