DesignCrowd is a crowdsourcing platform for businesses to post design contests for an element they need, whereupon designers compete with their skills to win the prize money. They have a sizable contingent of skilled designers who’ll offer up their talents, so you can rest assured that you’ll have a healthy selection of concepts to choose from. However, be aware that to get the best designers, you may have to invite a few of them to your contest, and then spend time reviewing, commenting, and critiquing so that they can make changes as needed.
