Once you set up an account, the gist of it is that you create your own pizza by picking toppings, sauces, and crust types (You can even modify or rename existing Domino's pizzas). Then, you try and get people to buy it. For each pizza sale generated, you pocket anywhere from 25 cents to 4.50 Australian Dollars ($1 AUS is currently about $0.94 US).
The site even gives tips on creating your pizza, advertising it, and leveraging social media.
In case any of you are raring to sign up, Pizza Mogul is, unfortunately, only open to Australian residents.
