A small idea to get customers interested. Perhaps you should run a blog giving out basic computer tips so you can promote your website. If not computer tips, then perhaps reviews or any sort of content really so you can get additional traffic.
As a bit of feedback, for your service comparison charts, it would be more presentable to have the lines lined up at the same height and perhaps add a couple pictures as seeing just text isn't very exciting.
Congrats on your business though. The website is nice and simple; I like it. Good luck :]
