www.elance.com It's a bidding site where service providers enter a bid for your project and you select which one to use with no obligation on your part. I've put about 6 projects up for bid and been happy with all the results. I currently have a project listed for a new website. You can get all types of business services done there, but design work is one of the biggies. If you ask for a logo expect bids from $25 - $200 with the high end including letterhead and business card design.
