Personally I like the design/layout and or colour scheme, but there is always a "but" firstly the homepage does look a tad cluttered, perhaps read Steves article on whitespace as it does explain things in a nice format.
Though looking at the design, the index or home is seemingly designed as a "splash page" as such it like many others does need quick facts and not a great deal of information, examples could be uk2.net, fatcow.com and poundhost.com, the more in-depth information should be within the item pages itself with such a design.
I like the hosting plans page though the order buttons are a tad on the large side?
Finally to WHMCS, you really need to integrate it badly.. Jumping from the site to the basic WHMCS when hitting ssl was a tad of a shock and it doesn't complement the rest of the site at all.
One other thing would be change "Customer Sayings" as it really needs to be "Client Reviews" or "Customer Reviews".
You also have a java error on most of the pages, I have a positive idea as to the reason however it should be easy to fix. However i can see those images steve cannot
Overall it's looking good though
