Youtube channel growth

I want to grow my youtube channel 3.2k to 100k this year with help of right agency or team for my social media handling, tags, hashtags, topic of videos. Google and youtube ads on video. I want everything done under a roof so that, I don't have to connect to someone else. This ll be a monthly service.
