Steve has an idea for an app. Can he get a company to make the app and pay him a royalty? Leo says that app ideas are a dime a dozen. It's the execution that's really more important. The idea alone is not enough.
Assuming the idea is marketable, he would then need a partner that can not only build the app, but will be able to market it as well. He can hire them via eLance. Leo advises that he look for partners rather than a freelancer. He should think of it more as building a business, more than just an app. Then he'll be ahead of the game.
