Hello there!
I have carefully read your project description, I understand it fully and I would like to do the job for you.
Although not a native speaker, I have been teaching English to various ages and levels for 15 years. I have also collaborated with many native speakers and all of them said they thought I was a native speaker.
My voice is gentle and mild and I speak with a mild US accent, although I can speak with a UK accent, too.
I'd gladly do a short sample for you.
You should know that I am highly responsible, diligent, and strive to deliver quality work on time.
If you think that I am a good match for your project, do not hesitate to contact me.
Thank you,
Tanja
