Voice file for english education app

I am looking for a reliable female voice actor to record audio for an English education app. The accent of the recording should be native British English. The total length of the project would be between 1-2 hours.

128 words to be recorded. each letter/ word per file, all files to be named accordingly.
I need the job to be completed by 28 April 2023.

I need someone who can deliver clear, clean audio with excellent pronunciation. If you're familiar with English language teaching/learning apps, that's even better - but not required.

As a freelancer, I'm looking for someone who has experience in recording crystal-clear audio with a professional standard microphone. This audio will be used within an app and therefore needs to be professional grade.

If you think you're the right fit for this project, I look forward to receiving your application. Thanks so much!
