I've recently been put on heavy JavaScript projects and have become fond of the front-end world in comparison to the back-end. I have always been good at proper markup and CSS, and coupled with AJAX, pretty animations, and dynamically generated content, it's become a much more interesting and flashy world for me. I would like to be able to continue to hone my craft in the same way that I was able to become proficient at back-end development with PHP: getting paid to do it.

How would I market myself as a front-end web developer with a strong interest in dynamic JavaScript-driven websites? Due to my strong background in back-end development, how would I find the companies that wouldn't waste my front-end skill set on simple HTML/CSS development?

And as a bonus, how would I apply this to being a contractor/freelance developer rather than a salaried employee? While I like the idea of being able to remain a part of my creations, I also dislike the maintenance phase of projects.
