Travertine importer for travertine - Industrial Products

I purchased travertine ash square pavio from one of the retailers in Poland for our bathroom. My wife changed design and this caused a serious issue. I am missing 20 tiles of the following format: 20.3x20.3x1.2 cm - just this format no others. I looked all over Poland for these and could not find them. Can you cut these tiled for me as a special order?
