DIY Centerpieces: Where can I buy crystals from in Pakistan?

Hi!
I live in dubai so wedding planners here tend to charge a bomb, and sometimes their stuff is really gaudy, i was thinking of making the center pieces myself since I know what I want:

Does anybody know where in Pakistan I can buy lines of crystals from, typically seen at weddings? I might even use them on the stage so I need a LOT. Can be Lahore or Karachi since I’m going to both places this year, at the best price possible!

Thanks in advance!
