Found this website that may help. About a 1/4 of the way down the page there's a spider that looks pretty close called a Golden Silk Spider and lives in Florida and the southeastern States. There's also a link there for this particular spider.

If this isn't it maybe also posting your pic there will get you some answers. Pretty spider (and I don't even like spiders LOL).
