Looking for Multi Vitamins

As we are getting ready to start the Christmas pie in the face challenge, I am looking for Vitamins. We need another 1500 one year supplies of multi vitamins . I have several leads I am working on, so I expect that number to come down. If there is anyone out there that would have some leads that they would like to track down for me that would be great. As well maybe you are part of a group or Church that would be interested in pledging as well.. every bit help.
