Welcome blong206b (that's a terrible name, by the way - as you've only written one Hub, I would really recommend you start again, and choose a proper user name this time (unfortunately you can't change it, you'll have to open a new account and ask HP to delete your old one).
You'll do much better to choose a user name that reflects what you do. For instance, I have a website called Bellydanceoz.com, so on some forums my username is Bellydanceoz. You might also consider using your real name - if people come to your classes because of what they've read on the web, they'll like the idea that they can meet the author.
Read Lissie's ballroom dancing Hubs before you do too much, for two reasons - one, you don't want to repeat what someone else has already done and two, they might give you ideas for what you could do.
You wouldn't think ballroom dancing was a big money-spinning subject, but the good thing is that although the audience is small, they're keen - so who knows, you may do well.
Have a think about what ballroom dancers want to know - maybe a Hub about how to choose shoes, or about keeping your frame? Once you've written a few, you can start joining ballroom dance forums around the net and when people ask for advice, refer them to your Hubs.
I NEVER backlead except when the man is absolutely clueless :-) I agree with Marisa- change your name which sounds like a human not a robot. Link to the videos using the video capsule so that you can watch the video right on the hub instead of having to click thru to youtube.
Good luck with making any money with dancing - its beyond me - unless you what to persue the reality TV route- and there is a fair bit of competition there!
