I doubt there is a singular answer other than to hussle. Try Upwork; Reddit; who's hiring; jobs sites with part time roles or "fractional" as they call it; exemployers and excolleagues; blogging; linked in; etc.
yep, pretty much doing this rn, not too intensely as I'm focusing more on actual work. what I haven't insisted enough or at all at: blogging and exemployers/excolleagues, perhaps I can also write a few valuable linkedin posts (I hate hashtags but can make an exception)
