Since you asked....
The spelling errors reek of amateur. If you're a PRO detailer then present yourself to the public, i.e. your clients, like a PRO. Some will say it doesn't matter, but it's a simple fix and only takes seconds.
Home page: Capitalize 'Rd.', after 'tinting' put 'experience'. (Did you read your site entirely before publishing?) Capitalize 'If' when starting a new sentence.
About Us page: Correct 'experiance' to 'experience'. The 'all caps' is soooo hard to read, plus it's like you're screaming.
Testimonials: You honestly don't have any? You've done some very nice cars, ASK! I used to not ask when I first started. I ask EVERY SINGLE TIME. I have stacks that I'll probably never use because my site would just be testimonials. And who wants that.
When designing a site, put yourself in YOUR CLIENT'S shoes. Why should they use you? 'Well I'm mobile and my prices are fair'. Ok, that's good, but make it almost like a 'bullet point'.
LOSE the side ads. Again it just looks bad. My opinion, but hey, you asked. I did my site using yola.com. It's FREE and is a wysiwyg-type drag and drop. Very easy to use and looks great. People ask me all the time who did my site. I tell them I did, which is the truth. Looks sleek, clean and tight.
Your colors aren't my first choice, but I have my own web site. The blue looks a little odd against the red, silver, white and black vehicles you seem to have showcased.
I did like your calendar. That's a great idea, one I may implement.
Sorry if I came off harsh or curt, but this is absolutely a pet peeve of mine. As professional detailers, don't we need to appear like we have attention to detail?
Good luck and I hope you make $$$$$$$$$$.
