I think at a bare minimum in Florida you will need a string trimmer, and a handheld blower or push broom with a dust pan. I would spend the $150 on a commercial straight shft trimmer. You can do both "weedeat" and edge for now with this with some practice. Also, you should buy a pair of flat hedge shears, long handle cutting shears. Not having that stuff will cost you business and not having the hedge stuff will leave a lot of money left on the table. I'd say you need to invest the $250 bucks minimum before going out to get work. Trade your car for a truck too. You can always make money with a truck in Florida.
