illustration

I am looking for an illustrator to create the perfect book cover for my project. I have a clear idea of what I'm looking for in terms of style and content; I am looking for a cartoon/comic style of illustration, and I have specific ideas for characters and elements included in the illustration. This book cover will be used for marketing materials as well as personal use. The illustrator must be able to convey my desired vision and bring to life the characters and elements that I have described.
