Time Team Christmas radio ad

I’m a radio producer with the Christian charity Reach Beyond. I’m producing a 30 second Christmas radio ad in the style of ‘Time Team’, on the theme of uncovering the real meaning of Christmas. I’m looking for a male voiceover, ideally a Tony Robinson sound-a-like (slightly high-pitched, London accent). Also a Phil Harding sound-a-like (West country, bit gruff), or a Carenza Lewis (female, southern accent). I attach the script for reference.

If you might fit the bill for one of these voices, do get in touch - ideally by/before Friday morning 25 November. Prepared to pay a fair rate, but with our charity status in mind. Some direction may be needed. Thanks,
Bruce Gulland
