Conver my celebrity interview videos into viral YouTube clips

I have just launched my YouTube channel which currently consists of shorts/exercise videos for my app. I want to expand on this to host long-form videos that elevate my engagement and convert my YT into a money making machine. I have lots of long form celebrity interview content (still on the health and fitness theme) and need someone who can:
* Edit them if necessary
* SEO them
* Make eye catching covers
* Write descriptions that draw views and subscribers

AI responses will be ignored! I need a proven expert who can actually make my YouTube fly! Thanks!
