My YouTube Scripts did 1.4 millions views, client ghosted me

My client is on the AI hype train, focusing entirely on his AI writing tool while leaving his YouTube channels unattended. He has multiple faceless channels that perform well, but with only ad revenue, he is not interested in affiliates, sponsorships.

I know what I do has value because I've repeated it in multiple videos, so it's not just a one-off thing.

What I do is replicate a similar style of video that went viral. I did '25 1970s Home Features We All Miss,' which got 370k views, and then '25 More 1970s Home Features,' which got 170k views, with a month's gap in between.

It's incredibly hard to find new channels to work on; any suggestions would be appreciated!
