Audiobook MP3 Enhancement for Amazon

I have an MP3 file of my audiobook created with Audacity that needs some professional touch-ups before I can upload it to Amazon.

Specific Requirements:
- Comprehensive noise reduction and cleaning for the entire audiobook
- Removal of unwanted background noise, primarily breath sounds

Ideal Skills:
- Experience with audio editing software (Audacity, Pro Tools, etc.)
- Expertise in audiobook production and enhancement
- Ability to deliver a clean, professional-quality MP3

Please only bid if you can ensure a pristine audio file ready for Amazon.
