I have experience doing audiobook work. So, this job would be no problem. To hear samples of some of my published audiobook work, find me on Audible by searching for Joshua Nicholson. I've narrated titles like "Dead Weight" and "Captain Hazzard".
You can hear more of my stuff in the new app Bound (available only on iOS right now). I narrated and produced "Purgatorio" and "The D.O.D.O. Files".
By my estimations, the book will come out to 2 hours. (I have a tendency to read slightly faster than the average 9,500 words per hour.) I charge $250 per finished hour (including partial hours) which comes to $500 for the finished product.
