I need raw video footage edited and audio remastered

I have raw footage of approximately 6 musical concerts that I require edited into final cuts. Each concert requires the following:
2 x short videos (each one musical piece long)
1 x long form video of full concert (approx 90min)

I can provide raw video and raw audio files. The audio must be remastered to be rich, deep and stereo if possible. While we recorded with 1-2 microphones in most cases, if it is possible to remaster audo into 4 or 5 channel that would be great.

I will send a sample video to shortlisted freelancers to show the kind of video work required - the audio in the sample video is however not the standard that we require and we particularly need assistance to remaster and improve the audio to be appropriate to our content.

The video footage that wee have is with 3 angles and in 4K.

Delivery of all final files will be required within approx 1 month. I will collaborate with editor during this period to ensure that titles of individual pieces are correctly represented where applicable.
