Would most community buildings allow you to rent a room if you are not qualified?

I am thinking of teaching Zumba part-time, I am fit and have been doing it myself for quite some time. I got access to T-Shirt making and a lot of facebook friends and family. However, I don't have any qualified courses or degrees in fitness, the ones I looked at in college lasted a year and don't offer much of a full-time job, even if you were lucky enough to get one. Leisure or fitness Centre's will take you on with no experience too, so it seems a waste to spend a year on a course that shows no importance to me personally. There are Zumba classes you can learn and go to and workshops but I don't fancy that. I have spoken to my fitness Instructor and she said it was hard-work, I have lots of ideas for dances and routines but I feel too awkward asking her more questions.

Will my local community building take me on to teach kids or adults Zumba and fitness sessions?

What's your ideas or any experience of this would be helpful.

What laws are there for this area of business? I have a first aid certificate, but nothing else. I do have qualifications in GCSE and A-Levels. but not in health or fitness.

Can I use songs and create my own dances legit like she has done?

Could I sell CD'S of the songs and perhaps some T-Shirts with my logo on legit?

Thanks in advance :) before you comment, don't be rude, like some are on here. I don't need a nasty answer, it's why I'm asking a question, it's yahoo answers, i'm interested in learning more. :-0
