Cinderella Full Size Carriage

I am having a cinderella theme wedding in august. I have a bunch of the little details, the centerpieces, etc, but I would love to have a full size prop of a carriage. Does anyone know where i could buy one at an affordable price? or does anyone have any creative ideas on how to make one. Im thinking of tent poles (course they would be covered with tulle and such) to make the roudness that I need for the carriage. Any ideas would be appreciated. Thanks!
