Help with Facebook Contest/Sweepstakes…

I want to run a contest to help promote my website and Facebook page. My plan is to have a sweepstakes when you must like my page to enter. I would like people to be able to get extra entries for getting others to enter or re-posting/tweeting the sweepstakes. I think I should use some kind of contest app and have looked at a few, I think woobox.com may be the best.
Has anyone done contest like this or used woobox or something similar? Right now I don't have any likes, do i need to get likes…
