Refinishing my Old Model Super Blackhawk

[ArmyBound]

I am wanting to refinish my Super Black Hawk to it's original condition. I was hoping someone with some experience could point me in the right direction as to who to send it to and how much it will cost. It has some holster wear at the tip of the barrell, one spot on the barrell is rough its smaller than a pencil eraser. Also where the ejector rod rubs the barrell needs to be finished. I also love the jeweling on the hammer but it's rubbed smooth on half the hammer on one side. Any info or advice would be much appreciated.
