Design seems to be good, however it is very similar to the Site5 site. About us, Hosting Features and so on should be smaller I think, and should be in different location.

so you going to sell hosting as well. What i get is your design are not attract enough which maybe too simple with few color. No sharp color or wording which do attract your traffic. i may suggest you insert some photo or some video talking about hosting. The pricing and the unlimited word may show sharper.
That my opinion.
It looks nice
The only thing I'd suggest would be do something vivid/bright with the background.
Maybe add some effects to the "About Us", "Hosting Features", and "Contact Support" Buttons, as Black Text on a Grey Background isn't that appealing.
I'd also center your Logo ;D
