After sending out voice over requests, I was surprised to find I had about3-4 replies in one day. One couldn't do the work I requested and another asked for money but was too expensive ($75). Although it cost me £5 I managed to get one of the voice overs to send me some audio. However there is a possibility I'll have another voice over clip coming soon.
But for now here's the one I have received, by Margaret Cowen.
