What should I expect to pay a shop that does metal work (mostly burglar bars and security items) for a 7-8 ft spiral staircase? I'd like to give my business to a local shop rather than one of the spiral staircase manufacturers I've seen advertise in mags and online. Plus I could avoid high shipping costs if I buy local. Anybody have a guesstimate of materials for an iron or steel spiral staircase (labor costs vary, this place should be fairly low because they're in a low rent district of Atlanta.) Thanks in advance for any insights!
