how do i get a agent in florida for disney channel?

I'm sorry, but it doesn't work like that. Disney gets it actors from a few top LA talent agencies. Those agencies get their clients from top LA acting schools, where they've been training in acting, singing and dance since they were about 6 years old. Disney - and all professional companies - are never, ever interested in beginners and the only way to get any real auditions is through a good agency.

You get an agent after you've had years of both training and experience. You can't get an agent as an untrained, inexperienced beginner. Most young actors get an agent either by being recommended by one of their acting teachers, or by having an agent see them in a youth theatre performance or a student showcase at a top drama school

If you check this kid's background you will find that she is 13 and has placed similar questions in 5 other places and even included a You tube video.
Sorry she just will not "find" an agent.
