Rigging commissions are much more expensive than 30$, for example Cillia's fullbody price starts at 3000,00$ ( https://cillialive2d.carrd.co/#price ), rigging from any artist will cost at least a few hundreds of dollars and 30$ are not enough to cover the price of a whole rigging.

that's fair, but why not make fully rigged and designed model commissions for people and have them pay a lot more for those instead of a public model example that is meant to teach other people how to rig models?
You would make a lot more money and people could learn how to make their own models as well.
