Childrens book co- illustrator wanted (8 B&W drawings)

I need 8 perfect images for a childrens book I designed the cover using a black pilot g-2 pen (at WM) and want that to be the "style" of all the drawings. I will "color" the drawings myself (so they match the cover) so they need to be black and white with a similar line thickness to the example I will provide (basicly just use as few stokes as possible so the lines are crisp). The person selected will be listed as a co-illustrator as this is not ghost drawing. The book will be for reading level 1 or 2 and it's about farming. Each drawing has been sketched out (so you know what to draw) as they will need to match the text. This is the first in a very large series of books I will be finishing. If you do a good job I will keep you busy as long as your available. Finally you need to be willing to do revisions if necessary. Similarly you need to be willing to let me make changes to or additions to your work as well. I need 48 hour turn around on the drawings but keep in mind these are not complex sketches. each drawing should fit in a 8.5"L x 5.5"W space.
