[vcf-midatlantic] Needed for museum: locker with shelves

We have a locker in the museum workshop. Standard 6 ft. tall, ugly, closes with a padlock. It's about a foot wide. It fits nicely into our available space, but it is relatively useless because it only has one shelf up top and there's no easy way to add more shelves I want to get rid of it and replace it with a similar unit (black or gray) but the kind that has several shelves from top to bottom. Anybody have one? Or can someone look online and find us one cheap that's within a reasonable drive for us to go get?
