Edit: I'm on my cellphone, sorry for spelling mistakes lol
OP, I was giving a small presentation to Real Estate Agents a couple of months ago before all this crap went down. I'm going to tell you what I told them. Take it it with a grain of salt if you like, but it's the truth.
Here it is.
To get big on social media, you need shootouts. This is plain and simple! Think of semi-biggest youtubers and you'll see that for the most part they all got big because someone else gave them a shoutout. Heck, even some world comedians because massive because of a YouTube shoutout (How do you think 'Fluffy' got famous?).
You have to do the same. You need to start connecting with YouTubers who will start giving you shootouts. For free. Because they want to. You will notice a massive difference between a paid shoutout which costs an arm and a leg, and a free shoutout that they do for you because they want to.
You can Google how to do basic PR pr relationship building on YouTube, but if I was in your shoes, I'd do the following (warning: this will be a long process, but in the end you'll make connections and you never know what extra gigs you might get with it):
It's quite simple really, but tedious. If I were you, i would identify YouTubers with 70,000 - 120,000 follower range who have banging tracks that you want to dance to. First, I would start a conversation with them telling them how much you like their music and fluff talk. Eventually you'd ask (or tell!) them that the next video you'll be posting will be about their track.
People with 100K followers will love it. Will give you a shoutout and most likely upload your video to their channel or at least a snippet of it. Free PR to 100k followers.
Do that for 5 accounts.
Next. Find people in the 120-200 range. Do for 5 accounts. And pretty much increase the account subscribers by 80k, building yourself up, making connections, etc. You never know which which profile account might be watching THE OTHER ACCOUNTS when they'll see your video.
Also, off topic, but as a side business I think you should open a dance studio. You'll 100% make money
