Neat and uncluttered design. Just feel that it is a bit squarish though. Also feel that putting a Google ad inside the web site tends to make it a little unprofessional. Users would wonder why you need such ads and would be more wary on signing up with you. Just my opinion.
For me i would simplify the site a tad and i would get rid of the google ads. I just saw an ad for service cheaper then what you offer so that distracts from what your site is about. I also don't think it's very professional as a service company to try and run ads as well. You want to be quick/efficient and to your customers needs. Perhaps a customer portal or something would be better for adsense..
I would also recommend only playing the active header once if possible.. seeing the animation for every page is sort of distracting.
