Artist Wanted to Illustrate Images for Rubber Stamps

I am looking for an artist to illustrate images of people/children doing various things that can be turned into rubber stamps. I want all of the images to be cutesy and whimsical. These images will need to be open line, so that once they are stamps, the person using it can color in the image. Final files will need to be sent in high resolution. I currently own a rubber stamping store online and have 2 different artists with 2 different stamp lines. I am looking for another to join our team. You work and images will still be independant, but sold in my store with other products. I release new stamps monthly, but with large production times, I typically like to have images for future releases ahead of time. You would be turning in sets of images at one time for multiple releases. While my store has only been open for a year, I plan to continously release new stamps. This job potentially could turn into a large on-going project.
