1. No money up front ! No exceptions. Pay when job is done and you are satisfied.
2. No baloney they are "Licensed". This is first clue something is terribly wrong since Florida DOES NOT license Landscapers. May see it on their truck or on a Business Card. But this part of the scam.
3. No accepting ones that knock on the door and ask for business. That again is good clue since these types of request for business are not allowed in the villages. (This also is a good rule to follow for anyone knocking on the door and asking for business !).
There are more things to remember but these are very basic!!
