I have to agree with the others that the font is too small. You only have about 7 seconds for most people coming to your site - so if they can't read it, they will leave.

Once you enlarge the font, it may take up some of the white space left over. If not, you may need to add more content or maybe some graphics as there's not enough content.

I'd love to see a picture of you. It's hard to tell who you are without a picture to go with it. And I'd be much more personal on the About Us page. People actually want to work with a real person, not a company. So what is it about you that makes you unique? What is it about you that only you can provide? That's your selling points. Be more authentic in your website and the clients will flock to you.

Great job. I'm proud of you for being able to do this. I have to have a webmaster for my site.
