Not a Contractor
Hill Country Hinge Notes writes about ornamental iron gates rather than selling it. Anyone wanting the work carried out needs a contractor, which this site is not.
Corrections
Published guidance is reviewed and amended over time. Standards change, materials are discontinued, and prices move, and a guide that has not kept up is actively misleading rather than merely stale.
How to Choose a Firm
For finding a contractor, the reliable approach has not changed. Verify licensing and insurance directly with the issuing body, get at least three written quotes, and ask each firm for recent local work you can look at.
