whoever you go to, just set expectations up front. if you want a 100% perfect job, let them know.
Also, I would look into what they know about "hydrogen embrittlement". Basically, when you chrome your wheels, they get more brittle due to what's known as hydrogen embrittlement. The solution to this is to bake the wheels in an oven VERY soon after chroming, and they get backed for a set period of time at a certain temperature, which alleviates the problem.
For most show chrome parts, it's not an issue. For wheels, I would make sure they take this step. if a wheel breaks, it ain't pretty.
Ask to see samples of past work too - that will tell you how good (or not) they are.
