Since I am not in Florida, I do not know installers there to recommend. I only have suggestions as I am also having my 2013 M5 paint film protected.
My only suggestion is to go for custom install. Some shops use pre-cut sheets (supposedly computer cut for specific cars) which may be fine for a week or two, however, when dirt start accumulating, you will easily see the edges of those pre-cut sheets. Personally, I would insist on the installer to use 60" sheets cut in such a way that allow for over the edge folds so no seam/edge is visible. Areas I had wraped are front bumper, full hood/fenders, headlights, side sills, mirrors, fins, rear wheel arches and rear bumper.
