I use creative hotlist to search for freelancers mostly on a per project basis. it's also a great site if you are looking for a full-time creative person, or for work for yourself.
categories of creative talent include:
animation, architecture, art, art/creative direction, cinematography, curating, print and web design, editing, engineering, illustration, information architecture, photography, production, programming, project management, proofreading, public relations, and writing.
if you don't have time to search the site, post a project/job listing. you'll be amazed at all of the skilled people out there. my only advice for the post is be really specific about the project, and the type of person you are looking for. good luck!
