For future reference, a QT doesn't have to be elaborate. Rubbermaid containers and a simple HOB filter is often enough to get by if you keep up on water changes. I always keep a container of sorts and stuff handy for 'just such an emergency'.
I had heard of people using rubbermade tubs as sumps etc. tut hadn't thought of using one as a QT. I would imagine the opaquic sides would help the fish relax as well.
They work quite well, and you can get some dry base rock from the LFS or use pieces of PVC pipe for hiding spots to help the fish feel comfy. When the QT is done just soak the stuff with a bleach solution, let it dry and put it away for the next time.
