I don't know where to get it, but I do know that anything as glossy as chrome applied like contact paper is going to be VERY difficult to have look perfect. If you are doing a flat space of any kind you may be better off with an actual laminate, and even then the area will have to be completely clean. At my summer job we were laminating with some brushed aluminum (no where near as glossy as chrome) and even that showed any imperfections like they were huge zits on the face of the finished product.
If the contact paper is re-positionable then you may not be too bad off, but whatever the case, my suggestion is to have the surface it's going to be applied to as perfectly flat, smooth, and clean as possible.
