Hello Ms. Yorke,
I can produce an audiobook for you. I have a handful of authors that I work with regularly on projects similar to yours (short works of non-fiction). I do all of my own recording, narration, and sound editing, and I work within the ACX parameters for Amazon audiobooks. You can see other works that I've produced here: http://www.amazon.com/s/ref=dp_byline_sr_all_2?ie=UTF8&text=Jalina+Shaw&search-alias=books&field-author=Jalina+Shaw&sort=relevancerank
I like to be very upfront about the service I offer. I have a home recording set-up and I am not a professional voice actor, so it's really not the same type of product as a professionally engineered studio mix. However, for most audiences, a basic recording that meets ACX standards is more than enough, and I can help you get your book download-ready in a few days at a basic price. $250 is the lowest bid accepted by Freelancer for this project, but I can probably offer you a better price, depending on your needs.
If you'd like to discuss, feel free to get in touch and I'd be happy to help you get your audio book online!
Best regards,
Lasha
