Would this be okay??????

I also live in Florida (East Coast) and we have a higher quality pole barn that has held up great and looks perfectly fine :) Also, It's alot cooler than the cinder block idea would be :) We built this barn back in 2000 and it looks the same as when built, hasn't had any damage through all of the hurricanes and has always kept the horses safe :) ok, well I hope this helps and good luck
