A couple of things..
1. Rollover effect on the menu and image buttons would be nice.
2. The background is dull and boring. Maybe add a gradient effect to it?
3. CSS effects (hover, etc) would be nice on links
4. Your big image in the middle with the girl.. has some funky mapping going on. If you click on the image on the top left corner, it takes me to your shared hosting plans. If you click on the image on the top right corner, it goes to the about us page. I would fix that since it doesn't make sense to have "hidden" links.
5. "Clients" in your footer should have a capital C.
6. The "About Us" link in your footer points to
http://crissic.com/about.html when it should point to
http://crissic.com/aboutus.html
