Cost of a single-color paint job?

I would consider having Maaco do my car after I do all the prep, but I wonder if they do color matches, since I want it to match factory color, and it's not an easy color to match (GA4 Light Gunmetal Metallic). I'll have to stop by my local one and see some of their work.
they have a paint book with all the paint codes and chips i'm sure you will see your color and they also had a good choice in custom colors that was from the house of color.............
