it looks like you've tried splicing two pages into one, but i really don't think it's working. the information architecture doesn't make sense. home = info + work samples? that's bad. it's too many different kinds of information (who we are, what we do and all the samples).
Not bad, kinda plain though. And change the contact section, those boxes are way to big and bad looking. Keep working on it, very plain as I scroll down the design.
I think your sevrices in the banner should be the second most importan thing in it and stand out and top of the banner would need some sort of bar/line not to be bug just to show where your site starts.
What we do section could have a rounded content box in it with no effects mayb gloss or w/e with a darker colour in it to make that stand out also.
