Hello Peggy, If you don't mind and can contact us directly I can get you a more specific price. We need to know what type of finish, if we are installing, jobsite are location etc. The basic starting cost of a similar system to this would be primer, finish satin black and installed locally about $130-$140 PLF, there are a lot of factors that go into a price so if you would like to call me I can get more specific. We do not do the wood cap, we make it ready to accept one. Thank you. Darla Ames, Northwest Stair & Rail
