Looking for 4-6 small drawings in black/white for a book. Book size is 8.5x5.5 which puts the max size of the drawings at about 7x4.5 (inches). I don't expect them all to be that big though, if any of them. The novel is a Christian-Fiction with familiar Christian stories like David, Samson, Ruth, etc. Audience is young-adults, so I'm not looking for kids illustrations or something that looks too much like a cartoon, but also doesn't have to be completely realistic.
Willing to negotiate pay, and your name/website will go in the book as well (if you want).
