Hi
I am a native Welsh speaker and I would be happy to help you with this project. I have previously worked on similar projects. I estimate this would take me around 4 hours to complete, therefore I propose a fee of $120 based on my hourly rate of $30/hour. I would be happy to provide a sample recording to show the quality of my work. Please let me know if this is of interest.
Kind regards,
Gethin.
