Children's Book

I am looking for someone to do a series of black and white drawings for a children's book. The style will be a contemporary anime style of teenage chinese children in ancient stories but with contemporary dress. I need them immediately since the author wants the book to go to the publisher by the end of the month. There will be 8-9 drawings per book and, if we are happy with the results, there will be a total of 13 books. I'm attaching an idea of what we're thinking.
