Pulling and swapping should not be all that bad. The first time I pulled my rear and passenger seat it took me about 30 minutes. The door panels might be a bit more of a headache if you don't have any panel removal tools (harbor freight cheap).
For selling, I see this being a giant pain in the @#%$^... good luck...
Size and weight make it difficult if not local.
