Comment: Re:Who did editing and printing? (Score 1) 98
As a writer who is doing self-publishing, my answer is to do it myself. I have significant experience with both editing and design, so I felt completely comfortable doing the work myself. If you don't think you're up to the task, you can always pay someone else. I've published through lulu.com and createspace.com, and both offer editing and design services. It's not cheap, but not terribly expensive either, and if you're not confident in editing your own work or coming up with your own design, it can definitely be worth it. I've seen plenty of self-published books where the author clearly should have taken advantage of these services.
On a quick look at Hugh Howey's cover design, I can't tell whether it's professional work or he did it himself, and the preview amazon provides does not include any copyright notice or artwork credit indicating it's his own work or someone else's. I don't like the cover design, and from the snips I read, I don't care for the writing style. It just doesn't grab me. YMMV.
I did two different covers for my book, one for the ebook, and one for the printed book, due to odd licensing issues I won't describe here. I personally prefer the second design (print version) to the first (ebook). Interestingly, cover preference on my book seems to be split on gender lines. Women generally prefer the unicorn leaping through a portal version, while men prefer the staring eyeball version. See for yourself here: ebook (first design) and paperback (second design)
