There used to be a flying school at Orlando Exec with a C206 on a Part 135 charter certificate. I couldn't find an Orlando 135 operator with a C206 on the FAA's website so maybe they've closed. There's still a school in the same premises, next to Showalter FBO on Herndon Av. Perhaps a call to them?
Alternatively, Trax Air has a Saratoga available if any 6 seat single would do.
