I don't live in Florida, but I can suggest that you get applications out as soon as possible if you are qualified to begin teaching in the fall. From your question, though, it sounds like you may be missing some education courses, which is exactly what my situation was. They are necessary for certification.
In my state, (North Carolina) there was a lateral entry program that allowed people without education degrees to become teachers, and take education courses while you teach. A quick Google search reveals that a similar program may exist in Florida, which is where I assume you're interested in teaching: http://www.altcertflorida.org/programOverview.htm.
My suggestion is that you look into that. Unlike in my day, most of the necessary education classes for certification are available online, which makes the burden of doing your coursework while teaching far less onerous. Some districts will even pay for your classes. Failing that, you may want to look into teaching at a private school. Teach for America is also always interested in non-education majors who are interested in going into teaching.
Best of luck, there is always room somewhere for qualified teachers.
