Voice artists needed, various accents for quick short recordings

I have several short voice recordings I need for a project ASAP.

Looking for a few voice artists to record a small speech and send the file back.

Characters needed (gender & accents):

NATASHA, Female, British, English
ADRIANA, Female, British, English
AMY, Female, British, English
ISLA, Female, British, Scottish
MEGAN, Female, Singapore

DAVID, Male, British, English
TAD, Male, Australian
Stephen, Male, Australian

All speeches are short - just a couple of sentences each - to be provided when accepted.

Turnaround is quick on this one. I'll need all recordings by close of play 18th December.

Recording for a high-profile corporate event, so quality of recordings need to be very good.
