My area of expertise is making the footage recorded with crappy equipment to look and sound less crappy.
I can reduce humming/hissing noise, fix grainy video, adjust contrast, brightness and color, stabilize shaky footage, add any music, text or logo that you may have.
I just didn't understand your last line: "added bonus for helping to narrate into text" - do you need subtitling?
