British Voice Over (Male or Female) for Whiteboard Animations

We are looking for a British Voice Over talent for 3 short whiteboard animations - either male or female. The voice should be friendly, natural and conversational and slightly humorous/light-hearted. We have 3 short scripts currently in development, each will be about 160 words or so. The chosen person must be able to deliver the work within 24hrs of receiving each script. It would be great if you could send us a sample using the following lines taken from our script: Have you ever wanted to learn more about hypnosis? Or would you like to see a hypnotherapist to help you overcome an issue, but are not sure how it works or what to expect? Hypnosis can seem like an enigma and the more you read about it, the more confused you become. Only proposals with samples will be considered. Thanks!
