Taking a Video physically in London

I am working to create a video highlighting the "journey and lives" of my students who are studying in universities in London.

I require someone to take the video/footage of these students in a couple of locations in London. The video quality has to be high and professional please, as well as the sound quality. You will have to provide both the video recorder/camera AND the microphone. Since the video will be mostly outdoors, the microphone quality must be really good to prevent any "wind" or external sounds to be present in the footage.

The script and talking will be done by myself, but you can always provide some advice from your experience on where to take the video exactly etc.

Overall: I would like the footage to be taken sent to me, where the actual editing of the video will be done by myself later on.
Time: the overall session will be approximately, up to 3 hours during that day in London.
