It's one of my highest Patreon tier rewards (30/month). The commission usually takes at least 2 months, or 3 at maximum, depending on how big the update is so I can fit it into my schedule.
If you are interested, I advise joining the game Discord server for the details if it's possible to do in that form and then checking out my Patreon.
(My tier reward list is quite long, so it's worth checking it.)
