Please help me improve my sales copy

[orbitsys]

The URL is http://www.miramods.com

I just started a small web shop and would really appreciate it if the marketing experts can help me increase salse. I started it yesterday, and advertising on google adwords for "premodded xbox" and similar terms, has gotten 13 visitors so far. Now I know it is an improbability to get a sale from those thirteen, and im only paying $0.05 cents per click, so I can go through about 300 clicks and still make a decent profit per sale. Obviously though, I would like to increase the sales per visitor, and I am still learning marketing. The adwords campaign directs users to http://www.miramods.com/premods.php and then the other pages that must be effective are http://www.miramods.com and http://www.miramods.com/services.php and possibly the about page.

Basically I just need help on rewording or what other information/pictures should be added

Thanks for any help
