Start with the gaps, not the entertainment
Before thinking about a magician at all, map out where your guests will be standing around with nothing to do. In practice that is almost always the drinks reception, the stretch while photographs are taken, the room turnaround before the meal, and the slow middle of a long dinner service.
Those gaps determine how many hours you need and when the performer should arrive. Booking entertainment for a slot where something is already happening wastes it.
