Aside from the layout...issues...you should also rewrite some of the text on your site. A lot of it comes across as very amateur. Grammar errors, conversational tone, vague, bland descriptions...it's all very pedestrian. How long have you been in business? Any good press you can share? Any big-name clients in the local area you can mention? Are any of you certified? How many years of experience, combined, do you have? What Linux distros are you proficient in addressing? Can you handle Apache web servers? Can you configure Postfix?
If you're offering 'World Class' service, you have to convince your potential customers that this is really the case and that you're not just blowing smoke up their asses. After all, any idiot can download Ad-Aware, AVG, etc and run a few scans. What makes you different, and worth people's hard-earned cash?
I'm not trying to be harsh, but having worked for a computing-solutions company that promised puppy dogs and ice cream-farting unicorns to our customers while hardly ever actually fulfilling those promises, I tend to look at small IT maintenance companies with suspicion.
