What is the maximum number of Antminer S9's that can be ordered from Bitmain's shop, when it is available. I am looking to purchase 300+ miners and I would like to purchase all of them at once. I have contacted Bitmain about this, and they have not really answered my question and simply referred me to their shop and saying that they will be releasing more miners soon. So, before I get my financing and everything, I would like to know if it is possible to purchase 300+ miners at once, or in a reasonable timeframe.

Also, if anyone has any information about more direct contact with Bitmain, then I would really appreciate that too!
