Realistic skin creator pricing

Hi there, i am looking for skin designers to create skins for ORKADU. The plan is to release simple and comlex skins with different pricing (simple: 99ct, complex: 1.99)

A complex skin would be a skin that uses the inner and outer area of an Orkadu-Bubble. A simple skin occupies only a certain area of an Orkadu-Bubble. Ideas like Noses, Hair, Eyes etc. are simple, full "costumes" like a monkey, a celebrity or similar would be a complex skin.

What do you think is a realistic price per skin type for skin creators?
