People that get into a hobby for the purpose of making it a hustle tend to crash and burn (there is an occasional success, but rare) because they lack the knowledge and experience that comes with having been in the hobby.

The tabletop/Warhammer community is overflowing with wannabe commission “pro painters” who bought an airbrush and a bunch of contrast paints and immediately started advertising. They might get some bites, but commission painting lives off of repeat business and word of mouth. Neither of which are driven much by beginner level contrast painting and airbrushing.

I have observed that “very clever” people on the internet have a tendency to disregard solutions that are only partial, even if there is little to no downside to them.
