36" wide tanks?

[units0000]

[(sorry if this is the wrong forum)

I'm looking for a 36" wide 24" or greater deep, and 24"ish tall.

I'm assuming this tank size or one like it is custom/rare?

I'm thinking about a project, but I don't want to spend the $450 to have a 36X30X24 built. I'm hoping this size type is common.

Thanks for your input.]
