Hi, and thank you for taking the time to consider my bid.
I am a native English speaker from England, and I am sure that I would be able to produce entertaining and enjoyable voice-overs for your videos. While I don't have much professional experience with voice-over work, I have spent much time on stage and camera, for personal and professional projects. I have also been told many times that I have a voice that is perfect for voice-overs and audio books. I am well spoken (think Colin Firth, Hugh Grant, Stephen Fry) and I have a great ear for accents, so if you need me to alter my vocal patterns it shouldn't be a problem.
I'm looking forward to hearing back from you, and thanks again for considering my bid!
