We are a San Diego based company and have completed this process of slicing and building HTML & CSS (including HTML5, Responsive and mobile pages) for many of our clients using Kentico.
We can work closely with your development team if needed to ensure an easy integration for your developers from HTML templates to Kentico or can build the templates directly in Kentico.
We have been working with Kentico for over 8 years.
I would be happy to discuss doing this for you.
