Tech illustrations for textbook project

Work entails working with us to develop a style that will be used from here on out, then, creating the art for this title. All art is for a growing Texas-based educational publisher. The current book, which is just now being written, will have approx. 250 pieces of art. It is a Grade 5 Science book. All art is to be created with Adobe Illustrator. All art is black and white (not RGB or LAB). All text will be Verdana. Once the job is awarded, the art will be due in 6-10 weeks. Prefer partial deliveries, by unit or lesson. If it works for both, the work will be ongoing. And, yes, I prefer someone local that I can speak with! The document attached, G5S Art Style samples, is a collection of items from state tests. There are 3 styles: 1) Line Drawings; 2) Drawing with Perspective; 3) Illustrative art I need: a bid, showing total cost, broken into the 3 styles, with a price for each. Additionally, I need a bid to develop the styles, either separate or as a single bid. Thanks, Marc
