I am clueless.

How is it you get started in this business? 

How long do you need to have learnt before you can consider yourself good enough to attempt to go quasi-professional and offer your services to a restaurant.  How do you go about trying to get a restaurant job?

And teaching, when are you good enough to teach?  How do you get started?

Ugh, this business confuses me, I just want to dance.. and watching bellydance shows and attending 4 different classes is an expensive hobby..  I was wondering if I could use my passion to even out the score slightly.
