Where can i find or buy a dance floor or like gym floor boards that i could use

Question:

Where can i find or buy a dance floor or like gym floor boards that i could use to practice breakdancing?

me and my bro have been recently practicing and learning how to breakdance. we did fine just using a regular floor but now that we want to learn how to do windmills and headspins and that sort of stuff we need to be able to practice on a smooth floor. at first we used big flat pieces of cardboard but they wore out after a while. i figured we could just buy some dance floor panels or we could buy some wood panels that are used for a gym floor. i looked on the internet but couldnt find much....does anyone know some website or something where i can buy some stuff or like a place where i could get what im looking for...help please...
