You can post your creative project, naming your own budget and deadline. Projects can include logos, business cards, brochures, buttons, icons, websites, stationary, illustrations, banners, etc.

Then 15,000+ creatives can input ideas. You choose the ideas that are most relevant to you. If you don't get at least 25 entries, your money is refunded.

CrowdSpring also has a contract to protect your ownership, that is available for free.
