I would suggest you pre release a beta version with limited features and a 'Buy full version' button first for free, and post articles, gossips, blogs etc about the orignal version at websites where a lot of WWE fans gather and on other social networks, set a standard price too, because people think 'too cheap' probably isnt good so many may hesitate to buy a 1$ app, as they may think it lacks features etc

If you need any help, dont hesitate to ask.
