Help grow Youtube channel Account

I need you to help me grow a Youtube channel account for a friend. This includes optimizing the Youtube SEO, and more to increase views and subscribers of the channel.
This channel currently has 151 subscribers, 36 videos and 4,006 views.
I am looking for someone who can deliver and bring me the best results, so that we can build a long term relationship. If you can do this on other social media platforms (instagram, facebook, twitter), it would be an advantage.
Please tell me about a similar job you have done in the past in one paragraph.
