There are things I love and others I am iffy with:
I really like the header/banner, it is great and the colors are catchy, but you should make your name bigger and thicker, a lot of dead space.
I like the tabs, but a simple rollover to turm them that "X-files" green would be nice and the nav side bar is really long, and it doesn't need to be. Either move some of the links to tabs or shrink the font or back off on the <p> margins-tons of dead space.
I like the columnar layout, but with such a nice banner graphic you may want to include some aspects of it in your column borders, that 3-D grey bar would be sweet.
The pages are so very white, which helps readability, but is kind of boring.
Love the content, I found useful articles...
The photo of you on your intro page is nice, I like the border lines, you may want to incorperate that into the general layout.
Overall I like it, just a few small changes would make it pop out and be stunning.
Cheers and good luck with your business,
