An illustrator or graphic designer

I am looking for an illustrator or a graphic design who can create a series of images for a project that I am working on. It's a mobile app to teach kids to learn basic number sense. The theme will be space, hence I need some one who can produce the images for me. I have everything that I think I would want. I need this job to be down straight away, so only people who can complete the job or part of the job in the next 3-4 should apply.
