Help!

We're considering purchasing a new home about a mile away. I currently have
an 1,100 pond with 3 large (20"+) Koi and assorted goldfish. I don't want to
leave them behind but I don't have the time to build a new pond before we
move. I need some creative ways to keep the fish alive until a new pond can
be built. An above ground swimming pool? An old hot tub? Any ideas will be
greatly appreciated.
