Bread Maker Recipe for Gluten-free Pizza Crust

My nephew is coming to stay with us for the weekend and his favorite food is pizza. The problem is he is on a gluten-free diet due to health problems. I am looking for a easy way to make a gluten-free pizza crust. I was thinking about just switching out all-purpose flour for rice flour, but am a little afraid that if it doesn't turn out I will be out of luck. Does anyone out there have any ideas or recipes? Thanks.
