I did some quick checking and it seems that Florida has various state-run medical detox facilities and rehabs all over the state. I spoke to a guy at Recovery Connection in Ft. LD (800-993-3869) who said you should call 850-487-2920. Apparently the folks at that number will direct you to various facilities in different areas. He advised that that you need to be prepared to call more than a few, as demand for the free facilities is high.
I have a friend here in WV, with about 15 years of solid Recovery, who has a brother who runs a very low cost rehab somewhere near the Gulf Coast of Mississippi. I put a call into him for details.
There are LOTS of the private facilities, but as you no doubt know they don't come cheap.
Thank you for taking the time to do that. :)
