Need help cloning 15000 SD cards in China

I would like to ask you if you can help me or know some company which can help me in a very special issue. For an open source hardware project we would need to write 15000 SD cards, all from the same image.

Our problem is that we’d like to use Sandisk cards and Sandisk does not provide such service, thus we are looking for someone who can do it for us, in China.

I don’t know if this is the best forum or not to ask it, please direct me to the right place if I’m looking at the wrong one. Feel free to contact me in PM.
