Where can I find a cake box big enough for a 12 inch square cake? It's going to be a wrestling ring but I can't find any boxes large enough...suggestions??

Most cake supply stores should have them... remember you need a cake large enough to accommodate the board, not just the cake (so a 14 or 16 inch box). Try globalsugarart.com or one of the other supply sites if you don't have a local cake supply.

Both my local cake supply store and restaurant supply store carry big boxes.
