first impressions are great, the layout and color scheme work well and i like the simplicity of the menu. nothing too complex and flashy but it looks professional and suits the purpose the only thing i would change is add some images in there to break up all the content, at the moment it just looks like a mass of text other than that, nice work
True on both reviews, the image to separate the content and the side bar should align with the layout height, well not necessary but it would look better in my opinion. Another thing i didn't actually like was the top menu, yes it is simple and cool, but the background is dark gray and the active links color is black which makes it a little difficult to recognize. The menu is important for your site, so make the menu text color more visible and i would actually ad 2px to the menu text size. Other than that, it looks okey on view ) ... well, the coding side..eh, table based layout, thats all i can say.
here's what I noticed. For a design firm your website should be indicative of the design principles you're going to use. Your site isn't going to be indexed well due to the nesting of tables. I'm counting up to 4 deep in the content area and 3 deep in the navigation area. Other than your title text, the first thing a search engine is going to care about doesn't show up until line 45 (for your horizontal menu), line 75 for your menu, and line 143 for you actual content. Do you really want to force the search engines to wade down nearly 150 lines to get to your content? I'm not saying that you should forego tables and use CSS. I like tables when they're used correctly. I also like CSS when it's used correctly. Just as an example (and I'm not saying that this is the best) but if you look at my site (springcypress.com) it basically has a similar layout (2 column with header and footer navigation on the left). However the entire page is only 47 lines. Which one do you think is going to be indexed better mine or yours? I'll also agree with the other commenters and say that there is an awful lot of text on that page so much so that it overloads the visitor with information which means they'll move on to something else. Focus in on what you're trying to sell. Break the content up into smaller chunks spread across multiple pages. Also nitpicky stuff here... the images in the upper right hand corner should be image maps.
