Let me give you some constructive input from someone who runs a commercial website.
1: Your page title stinks. "Home". Very bad. Put your company name in there. This is a powerful ranking factor for search. Keep it to a few words, but make them 150% relevant to your site. Make it good, small, and do not waste a single character.
2: Your keywords are redundant. Get rid of duplicates. Duplicates = spamming.
3: Too much text. A paragraph or two is enough. If you find yourself doing more than that, it's time for a menu with pages to browse. People like content, not a single front with all the information right up front. Too much information is WORSE than too little. ( Why? You wasted your time making something nobody will read. ) Business writing is an art form. Once you get it down - you'll be very happy with your efforts. The trick is to say as much as possible in as few words as possible. I bet you, if I took that entire site - I could cut down the text by 80-90% with some work. Put the effort in - it'll pay off.
4: Make the FIRST couple sentences count. People don't like reading. You've got to catch their attention fast. "Sick of paying too much to repair your computer? We charge fair prices for service. We'll get your system working and you won't feel ripped off when you walk out." ( etc. Quick, simple, to the point. )
5: See your price list? I'll give you a very powerful phrase you can stick right as the first line: "FREE ESTIMATES! CALL US!"
6: You wrote a lot, already did the work - use it, but somewhere else. When you chop up your pages and make it with less text - offer up the option to get MORE information for anyone who wants to read about it. For each service, you can have a link: "Click for details" - and when you click it, there's a whole page dedicated to whatever. ( all that text you wrote. )
7: Some of your images are grainy. Grainy images = unprofessional. Get better quality, crisp images. It's better to use NO graphic than to use a low quality graphic.
