Audiobook Adaptation

Right now, I am working with a narrator through Audiobook Creation Exchange (ACX)to create an audiobook version of the first book in the Amderesta The 3rd/4th Republic Series. Under the ACX Agreement entered into by my narrator, the first fifteen minutes has to be uploaded to ACX pending my approval or suggestions for changes by September 30 2012. Once I give approval for the first fifteen minute segment, my narrator is bound by the aforementioned ACX Agreement to record the entire audiobook by December 31, 2012. Once the audiobook version of Amderesta The 3rd Republic is available for purchase from audible.com, Amazon, and through itunes, any royalties will be shared between myself and the narrator.
