Hey nmr86,
You should really consider getting away from Times New Roman, it looks "outdated", you're a hosting related site, technology, bare that in mind, give it a modern feel, try using Verdana.
The blue header and sidebar seems, kinda bright. Try making it darker, or even a light gray, just to make sure it doesn't stand out as much.
The menu is quite nice, although it just looks kind of lost, where is it currently positioned.
It just suddenly stops, try to carry it on, or have the grey border extended down to the footer.
While on that note, also make the blue sidebar be extenable right down to the footer.
I hope this was useful.
