I would suggest going with a smaller header on the home page. Also perhaps having a little more or a little clearer/cleaner layout for the home page.
It is taking up about half the page on my work screen and the home information is about the same as what you could have for an "about us".
Definitely look for something which serves as a better portal for your services/products/offerings rather than being just an "about us" regurgitation.
I haven't checked out some of the other spots but it looks decent enough
Consider having your menu going across the top and the services being listed on the left side as an option, so it fills up a little more space.
I'm not a good critic
I'm sorry, but I am trying to be constructive
