Blur & Trim approximately 130 Videos

I run a real-estate YouTube channel and have just moved to a new brokerage, which means every existing video must be scrubbed of the previous company’s branding to stay compliant. There are roughly 130 videos in total. Each one shows the old brokerage logo on screen and, at least once, I mention the company name aloud.

The videos are currently set to private

Here is what I need from you:

• Add a tasteful blur (or other full-coverage method) wherever the old logo appears so it is completely unrecognisable yet the rest of the frame stays sharp.
• Locate each spoken reference to the old brokerage—no timestamps are prepared—and cut or mute that segment.
• Reset the video to public

This will be an in YouTube edit as I don't want to pull down, repost all of the videos, and lose the current views. I have done a couple myself so I know it's possible. You can check the 2 out that I have done here: https://www.youtube.com/@angela_porrelli/videos

A steady workflow is more important than rushing, but I would like a realistic turnaround estimate once you review the 2 references currently active on my channel.
