British Voice Over Artists Required

Hi
I am in need of a British voice over artists to do voiceover for a conversation between two characters in a script . We teach English to non native speakers and would like to help these student improve their listening skills . The objective of this conversation is for them to listen how two native speakers speak with each other in this conversation m. We need to start initially with 4 conversations. although it’s an ongoing project and there are 15 conversations in total and remaining will be done in next stage. I would need a female and male voice over artist for each conversation.i believe if we can find two people like friends or family members then that would make voice over quite convenient. We would like to start immediately so would be great if you can mention your availability. I’m attaching the first conversation between our two characters for which voice over is required.

Regards
Zain
