Where can I find silk, blue dendrobium orchids at wholesale prices?

I'm looking for silk, blue dendrobium orchids to put in the bouquets for me and my bridesmaids at WHOLESALE PRICES. Yes, they HAVE TO BE wholesale prices because my budget. For some reason all the places I've searched don't seem to sell the silk ones even though they have the real ones. I've looked at ebay, Amazon, Hobby Lobby, Joann Fabrics, Sam's Club, and several places I've found via Google but none of them have what I'm searching for. They are the only blue flower that will be used (because blue flowers are hard to find and tend to be a bit more expensive because of that) so I'm trying to avoid having to pick something else. I've been Googling for probably a month. Does anyone know a place I could look?
