Afraid to say if you go the Fabricated route you will be forced to pay for labor when manufacturing from new stock... So always look around... Plus it might be the best thing to add the classical look your heart desires...

Home inspectors when I've sold houses before, note when things are not to code and with our previous minor issues (like a hand rail being too thin?), they don't prevent the sale of the house, they just alert the buyer. Anyways, not concerned about this specific picture's accordance to code, just looking for the cost estimate. Palimpsest - thanks! That's what I was estimating in my head, great to know!!!

Follow Sabrina's suggestion or use something similar, stay away from the railings in your 2nd picture they install them in warehouses, and the 3d picture railing is the iron porch railing they used in old houses or in older bi-level homes everyone is ripping them out and replacing. I know iron railings cost is much less in comparison but you have a beautiful stairway don't mess it up with some cheap iron railing, especially when the stairway is being the focal point when you enter your home. Good luck

What is not to code? IMO the same type of railing in white probably would work but I would like to see the front door.
