Thank you for your consideration. I have a number of voice samples available in my Freelancer portfolio, or can provide voice samples via PM for your review. You will find in my samples the deep, assertive voice you are seeking, and I have done a number of audio books in the past.
I look forward to working with you, and can provide the turnaround requested. The price, which I realize is substantially above your budget, yet a fair market rate for audio books, includes recording and post production.
Thanks again, and have a great day!
Chris.
