Getting parts plated is the best value for money part of a restoration bar none in my opinion. I normally get mine done through a mate who runs an engineering company and they get sent to whoever he currently uses, I will ask him where he sends them. I do know they vary greatly in quality of the plating as well so it's worth getting a good recommendation.

I would also recommend cleaning the parts on a wire wheel before you get them done, they will come out better. You should be able to get silver, black and gold pasivate finish.

How did your vapour blasting come out?
