Edit Existing Animation and redo voice-over with slightly different script

I had this video done by Mitja on PeoplePerHour: https://d3v9w2rcr4yc0o.cloudfront.net/uploads/stream/2015/03/502742/09220007/ACC.mp4

We were very pleased with it. We now require a few changes to it but Mitja has been stringing us along for at least 6 months to get these changes done! Now I'm looking for someone else to be able to take the video and tweak it slightly.

A new final screen (the one with logos, etc on it) and a slightly re-worded voice over (I have the new script) is the job basically. Full details of all of the changes and the new script are below.

Mitja has not supplied the source files unfortunately and hasn't responded for several weeks now.

If you can find the same voice over guy that would be ideal. If not, this guy seems like a close enough match: http://www.stevehudson.co.uk/index.php?p=72443&fuid=254248

Here is exactly what needs to be changed:

Below is an explanation of what needs to be changed:

1. Cut out the section referring to ICO - 1:09 to 1:15

2. Change logo on ‘Permission’ from Civil Aviation Authority to Air Safety Support International (ASSI). (https://d3v9w2rcr4yc0o.cloudfront.net/uploads/stream/2015/10/18987/20190903/ASSI%20logo%20p-tone.jpg)

Audio needs changing to ASSI accordingly (as per new script).
