I like your design. What I used to do was have an account somewhere that has a company profile for you, that has reviews. (I chose WebHostingStuff... Wouldn't recommend it 100% but it's good.)
Webhostingstuff was okay, because it had uptime reports, and reviews, and you could post your plans on it and such.... I never got business from the site itself because I didn't pay for advertising, but it built confidence in prospective customers.
You need a way to sell yourself too. Right now you're just another host.... Either specialize in a type of hosting, or do something that sets you apart. (Some people give away iPods in contests, some people stress a certain aspect of their company that sets them aside from the rest like true 24/7 support or something)
