Hi,
As a native German speaker, I would be more than happy to complete this project for you. Not only do I meet the basic requirements of recording in a quiet, echo-free environment - but thanks to my background in translation, I also deeply understand the importance of precision and clarity in language.
Regarding the offer, I understand that the cost is $8 per 89 short sentences recorded--a fair and competitive price. In terms of efficiency, I won't take up much of your time as I can complete this project confidently within 10-15 minutes.
Furthermore, while this may seem like an easy job for experienced freelancers, as someone new to this platform, it would mean the world to me if you gave me the opportunity to prove myself. I am extremely motivated, detail-oriented and promise not just proficiency but a fresh perspective to learning while delivering outstanding results. Thank you for your consideration! I look forward to discussing further details with you.
