Advice?

[Shadowriser]

Hey I started a business finally after years of thinking about doing it. My business is in computer repair and setup. My question is what are good ways to market without costing an arm and a leg? I am currently working on a web page with a RL friend who does it for a living. I have posted on Craigs list but need some ideas.

So far my company will be willing to repair, make new computers. In home network setup and new computer setup. Also want to start in data backup. After seeing how much Bestbuy's Geek squad rips people off I was shocked.

Also any services I should think about adding? Thanks in advance for any ideas you guys have
