Hey Crazy House -
I know this bid is a little over your budget, but you need a mentor/consultant to teach you how to to do titles/keywords and descriptions properly to optimize the chance of Youtube promoting you in their Search and Discovery. Otherwise, you'll be handing the reigns to your channel over to a complete stranger - as there is no real other way to do this unless you're physically doing it on your channel (None of the gimmicks people practice ever truly work)
I could teach you this over video chat and you'd come away with a much better understanding of why you're not ranking.
My name is Paul and my channel is Don't Turn Around, which has slightly over 250,000 subscribers. You can look at any of my videos to see my ranking experience (on the channel I have 10+ videos over 1 million views/50+ over 100,000 views)
Aside from the rankings, we could also talk about some other things you might be overlooking that have slowed your growth down.
Best,
Paul
