Seeking frontend/UI designer for new startup

I'm working on a project that allows users to receive notifications of events, both scheduled and automated, via a variety of delivery methods. While I've already crafted a majority of the backend, my frontend design skills are severely lacking.

I'm looking for someone to help design the user experience. Basically, I need someone proficient at graphic design, HTML/CSS and Javascript. Most all of the backend is coded in PHP, so while PHP knowledge is a huge plus, it is not necessary.

This would be a contract job, trade-for-services, or however we end up making a deal. I'm not looking for a full-time employee right now. I'm near Philadelphia, but your location doesn't matter.

I'll be more than happy to fill you in on all of specifics of the project via email.

If interested, email me at barlo@barlo.net.
