I would suggest to you with all my heart that you check out K12 schools and see if there is one in Florida...there is one in almost every state. They have an extremely advanced curriculum. It's an online school...you do the work at home, the children participate in various online classes (at this age, only one or two a week), and you can work at your own pace.
Just to give you examples of how advanced the curriculum is...
In K History, my daughter learned the continents, MANY countries and cultures, and various rivers and mountains throughout the world. Now, in 1st grade History, she has learned fairly in depth about ancient Egypt and Mesopotamia, and we are currently studying Greece.
Their phonics program is excellent...my daughter, who is in first grade, is reading at a third to fourth grade level and I attribute this to their excellent phonics and language arts programs. They are exposed to everything from fairy tales to classic literature, classic and modern poetry, and everything in between (think "Danny and the Dinosaur.") :) My daughter is getting ready to start 2nd grade language arts. She is a semester into 2nd grade math, in which she has been adding and subtracting 4 digit numbers both traditionally and in her head, and is getting ready to start multiplication.
This also shows an example of how they can work at their own pace.
When I started her in K with our K12 school, I was concerned that it would be too easy because I had already done two years of homeschooling with her, from pre-K through 1st grade curriculum that I had purchased. I was so shocked to find out how advanced (but doable) their curriculum is...really great.
One of the perks is that the school provides you with the curriculum for free (this includes science lab equipment, all the books to read, all the text and workbooks, a globe, art supplies, and a computer/monitor/printer.) They even pay for return shipping on the things that have to be returned...they send you the UPS labels and you just ship course books back when you are through with them. (Of course, you keep workbooks, consumables, etc.)

I so highly recommend this school that I can't say enough about it! Even to do it for a year or two would give you a clear idea of what it takes to educate your child thoroughly at home to see if you want to tackle it on your own. I love the fact that I no longer have to design curriculum or worry that my child will be missing some key component come state testing time. Our K12 school, MNVA, has one of the highest accreditations in the state and continually pass the "No Child Left Behind" markers. :)
