I think the concept is there it just needs more detail. If you're just asking if this looks realistic enough to be a site then it definitely is. If you're asking if people would use it how it is now, I'd assume not.
So
10/10 for concept
4/10 for Design
I think that it is fine. The color red is hard on my eyes but many like it.
When buying hosting people want ease of usage not how pretty.
As Sp32 already said, concept is great. But you need to work on details such as that vertical line, but make a dotted line 1 or 2px's. Order now button shouldn't be in the main column, as that's the "Why Us" page. Instead of "Discount Coupons" you should add "Important Clients" and small buttons of their sites.
Work on the text colors a little bit, you forgot to add the footer. It should contain Site Links, partner links, copyright info, and such...
