Custom Spiral Stairs?

landmark

Wondering if anyone here has ordered custom outdoor sprail staircases? If so, any info on some companies would be helpful and some of the options, troubles you had. I am looking at getting a 8'H 6'w spiral with some type of victorian or gothic spindles, prefer aluminum but am having a problem finding anything, even galvanized steel that the customer likes. thanks
