Most of the time I manage projects on my own, but I enjoy bringing in other people to work with me on certain aspects of a site like the Design, or a Store feature, etc. Here are some great people I have worked with so far, and are the ones I’d recommend talking to if you need someone in their chosen field;

Graphic Designers
Erica Schmerbeck
Donna Leys
PHP Programmers
Ruben Rickard
