Tower Vases

I am desperately in search of 50 silver tower vases for a military banquet. Probably 24`` or better? At this point I`ll consider almost anything I can find - including any creative ideas anyone might have about how to use some sort of non-vase item to achieve the same affect. So far I have been unable to find anything in silver but I know they exist because we had them at my wedding not six months ago. Any help would be greatly appreciated.
