The licensee pays to use the licensed material. Done that way nobody can complain. Much like a movie studio paying the author to license their book for x years, paid up front, and possibly pay royalties on income above z.
When you license a piece of art, do you pay an up-front licensing fee or just royalties?
Up-front payments (actually advances on royalties) are only when the artist has a proven history. Most deals are made for royalties paid quarterly based on the selling price of the print.
Ergo, artists (or at least the ones the OP has been trying to contact) must not be rational.
