What's is a safe reliable site to buy flatback swarovski crystals?

I need about 1,000 to decorate a figure skating dress in jet black crystals.|||www.johnbead.com I am not sure which country you are from, but John Bead is located in Toronto, Ontario but will ship internationally at very reasonable rates. I have ordered a lot of beads and jewellery components from them over the years and have always found them reliable and give good service.
