Any recommendations for a reliable shop in Detroit?

What are some good questions to ask these guys?

Of course, "how many CL's have you done?" will be my first question.

Any other good questions I should ask...CL specific questions that you guys may have run across in your experiences?

I went to focal.com and found four dealers in my area that carry the line, I'll shop all four if I'm going to put some coin in this project. I won't hesitate to pay more if I get a good feeling about one particular guy.
