i have a six tier wedding cake to deliver without any help. I am trying to see where can i obtain boxes large enough to transport the cakes in. the cake sizes are 16" 13" 10" 8"6" and 4". I think I will place the 6 and 4 inch at the wedding site, but i wanted to put everything else together. i am open to all ideas. i even looked into going to home depot to purchase boxes but i wasn't sure.

moving/shipping companies carry nice, sturdy LARGE boxes...
