I am sorry that you have not been able to reach Chris, but he would be the one I recommend. He is a one man band working for a lot of big teams / organizations, but is truly the best at what he does.
Like many proprietors that serve this sport, what he may lack in availability, he makes up for with a great product.
If you just want name / numberplates and don't need anything crazy fancy, you can get that through his ebay store. Otherwise, I would try him again. He has a thread here too, so email him, PM him here, post in thread. You should get him.
