I agree about the google ads on an ecommerce site, though I shouldnt talk as I use them on some of my ecommerce sites as sometimes they bring in more money than the services the site sells.
As to the site, it does look quite good, but I dont think it would be the type that would convert to web design clients. Most people that would pay for a design are corporate type clients that are making money, and I dont think that design would appeal to them.
