Voiceover artist for animations about health research

We need 5 different VO artists - UK English fluent speakers (but not using a fake British accent) - with different profiles to provide voiceovers - each artist to provide a VO for a script approx 40 seconds in length. For use on the platforms of the health research institute.

You will need to convey serious important messaging expressed in as non technical language as possible but by the nature of the subject there will be technical health related words.

These need to be completed by March 24th - depending on number of applicants we will be selecting artists by 17th March eop.

Please advise total cost to allow for 2 rounds of amends and confirm capacity to deliver within this timeframe.
