Light touch editing on four videos

I am carrying out video interviews over Zoom, recording them and then posting them on my website. You can see an example of a finished one here: https://www.catalysis-advisory.com/video-library-andros-payne The videos vary between 7 and 16 minutes in length

Currently, the process is as follows:
1. I record the interview and, once I have my interviewees agreement, send the Zoom recording link to the son of a colleague
2. He takes the video - which is in MP4 format - then (a) trims the start to remove the moments before i start my introduction, (b) trims the end to remove the moments after we finish talking and (c) he adds in a front page with our logo and the title of the video (like in the example above)
3. The video is posted into a Dropbox account

The reason for this project is that my colleague's son is away for the next two weeks and I am keen to get the next four videos edited in the same way sooner than September.

One of the videos had to be filmed in two segments because Zoom froze on us. We re-started recording from a point before the freeze. So the two segments would need to be edited into a single file.
