Hockey Video Editing: Coach-Student Interaction -- 2

I'm searching for a skilled video editor who can help me isolate coach and student interactions in recorded feeds from a hockey rink to be able to understand their conversations.

I have a 30-minute recorded feed from a hockey rink of a figure skating lesson between a coach and a student. The interaction happens on the far left side of the rink where it is harder to understand as the camera is located in the front middle of the rink by the hockey box.

There are many other skaters at the rink at the same time, conversations, music playing, etc. I would like to edit the video to isolate that particular student and coach to be able to understand their conversation by amplifying the audio and reducing background noise.

The interaction starts in video 22T095954 at 3:25 mins, when the coach in a long coat and a blue hat calls 2 girls over. The girls skate around the rink to warm up and then they meet the coach in the far left back corner of the rink. The interaction ends in video 22T102954 at 3:55 mins when the coach dismisses the girl in the white vest.
