Can't locate the plants we want

Ok guys... I've exhausted my abilities to find this. We want to use dried Lunaria aka Silver Dollar plants for our centerpieces. We found a handful of people on etsy selling it, but their supplies are SUPER limited. Not to mention astronomical shipping costs, that would add up to more than the cost of the plants when spread around to multiple sellers. I can't find anyone reputable that is selling this wholesale. I even called around to local florists with no luck. We also do not have a florist hired for the wedding as all other flowers are origami.. Any ideas on where to find this? I've included pictures on what the plant looks like and the bottles we're using for the centerpieces. After thinking about this plant I can't imagine using anything else.
