I ran your website throught WebsiteGarage and you received a good rating overall, but on the important stuff you're site was quite good.
From a marketing standpoint you are missing a very important component: domain registrations box otherwise known as the "flycatcher".
Hosting starts with a domain but not all domains get hosting. It's a number's game, the more parked domains you control the greater the eventual conversion to hosting accounts.
Our experience is that you will see 20-25% conversion of parked domains to hosting accounts within a year.
So if you do not have a domain service prominently displayed you are losing potential business.
I recommend Tucow Opensrs http://www.opensrs.org
as a good choice.
Ask for Doug McDonald, a good guy.
