Artist to create images for book

We are looking for an artist to create 30-40 images for a book we are producing. The images will be in grayscale. We are d ---------- but the medium will be some combination of ink, pencil, charcoal, and ink wash. They will depict scenes from the book like when a grandmother holds her newborn granddaughter close to her face. We want the style to be unique and personalized. Please submit samples of your work. We are looking for a sketch-type feel that conveys emotion.
