Ranking a YouTube channel’s music covers

Hey guys !
I created a Youtube channel ,and I'm currently making instrumental covers (saxophone) for popular songs.I've released my first cover with high resolution audio and video.
Can any of you give me any tips on how to grow the channel quick and fast? How to get views, what keywords to use and everything and what should I do more to get my video ranked, should I share them in social medias like reddit … ?
I can pay even pay for SEO services or something similar.
And should I worry…
