I agree with Mary Lou that the green is really nice!
I also feel that the ads detract from the overall presentation and professionalism of the site.
I usually really like small fonts, but this one feels quite hard for me to read (maybe I'm just aging myself,

) maybe just increase the font size one pixel - you don't want your potential clients to have to squint...they'll not likely have the patience for it (studies show that people sum up the info on your site and decide if they want to learn more in the first ten seconds!)
