It's a long discussion, but first, the passenger door is worth about 1/2 of what a driver's door is, as driver's doors take most of the abuse. If someone has snapped the door stop on the passenger side or had rust appear on the door, swapping might make sense. Here in So Cal where all this stuff is common and rust-free is the norm, that's a $200-250 part. Where you are, probably closer to $400. You'll want a local sale, since that would be a huge pain to ship.

Rule of thumb for maximum $$$ is to break the door down and sell as parts: shell, inner panels, regulator and glass, outer handle, frame, mirror and top trim.
