I agree with 16k_zx81 about the home page being cluttered and the ACRBO image is a tad fuzzy. I also noticed that the homepage graphic is taking up a whopping 443kb of space. When I opened it in photoshop and reduced the quality to 60%, it still looked pretty good but only used 171kb.
Also noticed that the hover was set to black on the menu structure. I would set the text to change to a darker blue to indicate the hover rather than black out the whole menu tile.
On the scheduling page, you could convert all of those images to JPEG's, since the background is already white, and save a good chunk of space. Remember, the lower the file size on your images, the faster your site loads, which could give you better search rankings in the Google world. (

On the same page, I know you had to put in a lot of time configuring all of the images and information, but it's too much IMO to be on a scheduling page. It's very informative, however it's a ton of info to digest and sort through to locate a specific service. However, I am a fan of the client scheduling system as far as having the available times to choose from.
When clicking on "services" on the top menu, it takes you back to the homepage. I would either make a separate services page just for that link or redirect the link to "#" instead of the homepage so it stays on whatever page the user is at. Also the subpages of Services (Laptop Repair Services, etc.) could use small graphics to complement the text on those pages.
Payments, testimonials, and contact pages look good. May want to check the CAPTCHA code as that wasn't working for me. Images were't showing up.
Summary:
A little SEO work may be in order (optimize image file sizes, forcing the use of WWW avmobilerepair.com rather than without the WWW, etc.) If you would like me to help you out with some of the SEO, shoot me a PM. Other than that, I would decrease the amount of pics on the scheduling page and add a few to the Services sub-pages.
