Audio Restoration for Documentary-Style Videos

We're looking for someone to clean up the audio for a series of documentary-style videos. The sound was captured on a variety of different mics and locations, and we'll need the clips to be edited to cut together smoothly without any jarring sound changes (echo, ambient noise, pops, etc.) I've included a link to some samples of a few audio clips as a reference. If you're interested, we'd like to hear some samples of the clips post-restoration. Here's a link to a Google Drive folder containing the files: [login to view URL] The project will require sound editing for 10 videos of 60-90 seconds each, and we're looking to have the completed audio by the beginning of June. Let us know if you're interested, and feel free to include any relevant work samples or questions you have.
