Great site. Lots and lots of good, organized information.

OK this is where I get picky...

One thing that really stuck out to me was those testimonials on the first page. When I see those and there is no e-mail or website address attached, I assume the person made them up and the site loses credibility in my eyes because it's saying to me the site either gets no traffic or no one has ever really sent any testimonials. To me it gives the site a very amateurish feel.

I'm not saying that yours are fake because they may indeed be real, but I'm just suggesting that you only add testimonials with website addresses attached. Otherwise they don't look authentic.

I love how you broke down the steps, especially in your conceptualize section. Great job overall!
