I can only assume you're referring to the site in your profile: http://unifoursolutions.com/
If so, I think it's a good start. Nice XHTML, although, you seem to have the concepts down, you're still using Transistional. With that code you should fix the little things and go Strict.
You may want to change the body text to a serif font (Verdana or Arial are basic, but good).
Also, you may want to bump up the contrast on the navigation, perhaps a darker bg color?
Otherwise, looks pretty good.
