I'm thinking about starting my own business....

What would your Orlando Bloom business offer

Well the cafe should solicit any and all kind of seminars and performers it can to get people in. An open mic is always a guaranteed sellout, but beware of hordes of broke teenagers assuming it's a place to loiter and cause trouble.
So it wouldn't be that different from teaching in that regard just prettier surroundings. I don't understand the grill option...are you talking about a specially designed hibachi, or a cooking show?

How do you plan to start your own business? How would you get the money to buy the supplies to get started?

How's the economy in your area? Can you get buy on lean times? Here, restaurants are closing left and right. Including chain restaurants like Big Boy.

Consider also what the area you're in needs. Computer training is a big thing and you might be able to start doing that through your local Community Education or community recreation programs. (All the local schools around me have community education classes, such as computers, real estate, writing, etc. Local people offer the courses through the school, which puts out a brochure, handles the registration, provides classroom space and takes a slice off the top.)

As a teacher who knows what the job market is like, I wish you the best of luck.

I'd suggest working in a restaurant for several years before you attempt to start any type of eatery. More than likely, you'll be so turned off by the experience that you'll find some other endeavor to invest your hopes and funds.
