Children's non-fiction coloring book

This project is approx. 12 illustrations. No cover art needed. If I need more illustrations we will work out details before project is agreed on and started. Thick black and white line drawings for a children's non-fiction coloring book. Realistic with a cartoon touch. Professional yet fun. I will provide pictures/photographs (and possibly rough sketches I have drawn to show what I have envisioned) for the illustrations to be drawn from. Examples may include capitol buildings, state parks, historical figures, landmarks, etc. I want full ownership of these illustrations. I will need to see an example of your work in order for you to even be considered. Please include price, revision policy and artwork examples (preferably coloring book type line drawings). If I am satisfied with finished product this will turn into an ongoing professional relationship for several future projects.
