Audio Enhancement for Clarity

I need an audio expert to improve a recording. The goal is to reduce white noise and enhance clarity, as the recording is distant and hard to hear, possibly due to use of an audio jammer.

Requirements:
- Break down existing MP3 file
- Eliminate white noise
- Enhance overall clarity

Ideal Skills:
- Proficiency in audio editing software
- Experience with noise reduction techniques
- Ability to enhance audio quality for better sound

Please provide samples of previous work and estimated completion time.
