If your strength is design, working in photoshop and creating beautifull layouts; There is an application available for you that will transfer your PSD and create a WordPress theme. Visit Divine Project and check out their system.
The only downside is the Trial version has a size limitation and you will only be able to test a small layout. My review after installation is – If you are used to programming it by hand and already have a css framework you use, there is no need to adapt and loose your skill. For a Designer, it probably is a good investment. Make sure you keep learning how to edit themes by hand, do not fall on the lazy habit of always using a photoshop plugin for your WP themes.
Other benefits for designers using the Divine plugin are:
Takes a short amount of time
Minimal knowledge about php or css
Optimized for Speed
Gain total creative freedom
