Hi,
I can do this task well. I have transcribed multiple audios for various clients earlier as well. My usual transcription rates are $2/audio minute. But I am bidding here for $1/audio minute. As you mentioned that these are 20 hours in length, it means these are 1200 minutes, so I have bid accordingly. I am the top translator and transcriber here and on other freelancing platforms. I am confident that I can do this task well, thanks.
Best Regards,
Saadia
