We were thinking about a landing page that have the following:
1. Email subscription to access the contest
2. Like our page with like button
3. Facebook comment box where they can answer our question (this comments must be send to facebookpage)
4. Share option by facebook, twitter, gmail, we prefer with a referral link to give extra win chances to customer.
We already check heyo, viralsweep, shortstack, contest domination etc, but they don't have exactly this options.
Does someone have a solution for us that is working?
