How bad is your soil?
I found this website when doing a little research on Florida soils. You can search and look at all the USDA soil survey maps. You enter your address, set the area you want and it spits out a very detailed map. Once I found out what type I have (Hague Sands) I had to do a little research to find out what the soil is like/good for. It turns out my soil isn't too bad :) If I ever move I'll definitely be using this site.
