Today I found an interesting website for freelance illustrators, Illustration Ltd. This site has a good clean design & get straight to the point. As you search for artists by name, style, or country of origin, you’ll notice that they have their style list broken down to around 50 categories. So you really get to hone in on what you are looking for. For someone needing to find talent quickly, this seems like a good place to start.
For professional illustrators looking to list their talent, Illustration Ltd does have a strict application/screening process, advertising that they only accept about 4% of their applicants. So, we wish you the best of luck!
