ShortStack

ShortStack makes it simple for users to create Facebook contests, landing pages, campaigns and apps. This app allows businesses to create custom tabs and contests on their fan pages, and users can also add videos/pictures to their contests or promotions. The free plan includes unlimited campaigns, 5,000 campaign visits per 30 days, promotions, share functionality, and a Facebook fan allowance of 25,000. So its a pretty great option for small businesses. Paid plans start at $29 per month, and scale up to the All you Can Eat $499 per month - so you can move up a gear as your business grows. These fees are also reduced if you choose to pay annually.
