I went to your site. Looks good. Your prices seem fair. I like how easy it is to navigate and how you describe your process. It is also good how you provide a little education to help people determine where there vehicle falls into place.
may want to make sure the words that appear in the tab header are in caps instead of lower case.. other than that.. im hoping you asked permission from the owners of the logos you used on your page
Very well layed out and easy to navigate, and its not loaded down with an overwhelming amount of pics but has enough to showcase your work. It looks professional and I think it sells your services very well
