Fix voice audio of 21 files

Before you send me an offer - read until the end!

--------------------------------------------------------------------------------------------------------------------------------------------
I DO NOT CARE IF YOU HAVE 1000 AMAZING REVIEW, download an audio file from my drive, make a sample of a few minutes before making a proposal. otherwise, I will decline with "Don't know how to read"
--------------------------------------------------------------------------------------------------------------------------------------------

I have 21 audio files, between 20 to 50 min. I need the voice to be cleared up, normalized and sorted so you could understand what is said on them, removing any noise

here are the files.

please pick a file and make a 5 minutes audio file as proof you can take on the job

I will ignore any offer without sample work from my files, I don't really care if you worked for MTV or some mega huge blockbuster, as far as I care you can be completely a newbie as long as you can do the job.

please also specify how long it will take you to finish the job

thank you
