I can help.
I clear up badly recorded audio on a regular basis and whilst some audio is beyond repair generally if the plugins I use cannot solve the issues then they cannot be solved at all.
This gig is for audio tracks with a max length of 5 minutes.
I cannot do this for music tracks I'm afraid, it's aimed at spoken word, conferences, dialogue from films etc.
Basic audio restoration
Removing background noise and/or pops & clicks
