My company is starting a large scale web application, and I'd like to hire a designer to help with some of the pages (to create our general template, look/feel, and control set). Where is the best place to find a designer with some knowledge of usability? Would we be best looking on elance.com (or similar sites), or is there a better approach?
Note: The other question was regarding a web designer for an open source project ... this is NOT open source, and hence not a duplicate.
