Cheap tank needed to move

[Squirrelboy]

I'm moving again, rent + broken A/c leading to 400 dollar electric bills = moving into a trailer on my parents back lot so I want to get a 50+ tank for as cheap as possible so I can slowly move corals and fish over to the area before I move in around aug. so if anyone knows of any cheap tanks around that size for cheap, no matter condition as long as it holds water, then we are in good shape.
