This is the second time I have used 99designs for a book cover. Both experiences have been fun, worthwhile and highly productive for my money. You don't get one designer's idea of your book cover, you get many- all with different views, color contrasts and fonts. It's like a candy store for your book cover- all designed with your work in mind. The designers are easy to work with and more than willing to make multiple changes to reach the common goal of a successful transaction. Why hire a single designer when you can have a pool of them to work with? I highly endorse this company's process and admire how quick they responded to my questions.
