The designer's profile on 99designs indicates that they can complete projects within five days. However, it took 12 days to obtain the initial draft. The delay was exacerbated by miscommunication. The designer assumed that I wanted the endnotes at the end of the book; however, I wanted them at the end of each chapter. So, he had to do that piece of the job over. However, once I made him aware of my expectations in terms of time frame and accuracy, the response was was much more in line with what I had expected. Overall, Allan was extremely helpful in terms of publisher requirements. Also, he was very accommodating as far as revisions were concerned, and very prompt in his responses after the initial hiccup.
I would definitely work with this designer in the future and I would recommend him to others with one caveat, make him aware of your expectations up front.
