Building a stand is actually quite easy. Just takes some planning. Plus, you can build it any size you want.
The basics are simply a 2x4 frame and your choice of finish to wrap it in. Even though you are talking about 1000+ lbs., 2x4s are more than enough. A single 2x4 on its end could easily support this much weight, so no worries here.
Do a search. There are some great explainations and pictures.
