The navigation isn't clear enough in my opinion. At a quick glance the icons won't immediately be obvious what they mean to less-experienced internet users; especially since they're pixelated - use PNG image format for transparency instead. Hovering over them does display the title text but there's a brief delay in which the user could have skimmed over. The navigation should be as simple and straight forward as possible, especially if you're selling IT services.
The design itself is fairly plain as others have mentioned. The shades of blue you are using remind me of the default anchor colour and the lighting bolt just looks thrown in there from Google images. There's inconsistent spacing between elements so everything looks slightly out of place. Perhaps throw in some varied colours, look into typography, clean up the spacing, etc. Also I'd suggest looking at other websites that use a lighting bolt in the design, to see how you can better blend it in without it looking so constraint. Perhaps placing a very subtle picture of lightning in the background (not stretched or repeated though) would work better?
Functionality wise, it's pretty straight forward.. But is custom Google search really needed for 4 pages?
Hope this helps.
