Hi,
I'm new here and I figured I'd just jump right in.
I would still go one shade darker, plus you have some typos in your testimonials.
Your navigation order doesn't make to me. I want to know what you do at this site and I have to click to find out..Isn't your home page supposed to be your calling card? IMO your "how it works nav button" should be closer to your free quote form.
I like the simple clean look, its easy to navigate, its easy to read although you could go one size up in font. I had to squint a bit while reading.
Good Luck...I like it.
