For my part, I like it. It's clear, professional, and a site like that would make me want to use your services if I was looking for something like that.
However, I think it would be cool if, in the menu, the current category was highlighted in a different color as the on hover effect.
A fresh orange would be nice (expected, but nice ). You could also use the same blue as the one in your logo.
When clicking on your logo, I was under the impression that it would take me back to the main page, but nothing happens. Is it normal ?
Also, a contrast color might be nice (think about that fresh orange ).
Overall, very nice feeling.
