Is It Possible To File For Financial Aid To Begin In The Spring Semester?

I have never had financial aid before, but I am now hoping to return to college (in Florida) for spring 2008 and will only be able to do so with the help of financial aid. Is it possible for me to qualify for financial aid in time for the spring semester? If so, when would the deadline be to have all my forms submitted?
(I’m assuming I’m way too late for fall 2007, right..?)
