Hi!
Building a site exactly to a Photoshop design is what I do best. In my portfolio you can see examples (Artist's website) where I did exactly what you need to do now.
I work with Wordpress since 2010. Rollovers are no problem at all.
My background: I'm a professional Web developer from Russia. Used to work for international companies, but recently had to move to India. CSS, XHTML, Wordpress, Joomla, PHP, multilingual sites, responsive design, Bootstrap -- all these technologies are at my hands.
Please PM me to discuss your project.
