It depends on several factors. If you are only comfortable with temporary or semi-permanent tattoos that will not last long, those can pay you around $1k/tattoo.
However, you can make much more if you opt for a permanent one. Many people have reported earning about $10k per permanent tattoo.
However, the final offering of skinvertising depends on the size of the tattoo and the place where you want your tattoo. Areas like the back, upper arm, and belly are significantly visible.
So, you’ll get the best price if you select those places. You can also select eyelids and feet, although they will fetch you less money as they are less visible to the public.
