Think this guy deserves some nice feedback, so I figured I would give it to him....
For a very reasonable price, http://www.provoiceusa.com/
provided me with my phone greeting (just ordered a after hours greeting from him as well). You can call my number in my sig, after hours just dont push any buttons, K!!!!
Anyways, I emailed him with what I was looking for (in this first email i only told him I was looking for a basic greeting), and he told me $30 for 30 seconds. Music is an additional $10. I jumped on it, payed him, next day about mid afternoon my time, (he is in PST timezone, I am in EST, and I email him about 11pm my time) I had my copy. Was good right off the bat, so I did not need any revisions.
Basically, if you are looking for a voice over (I was actually looking for a female voice over, but with his prices and quality, I could not turn it down), I would recommend him 100%
As a last note, I want to say, I have no affiliation with him, just found him on google. I actually dont even know his name (well, it might be in the email, was that is not the important part of the deal)
