Sale of product per pack

[burotica]

Hello,
I try to create products:
The products are pillow cases, which may have the size 40 / 40cm or 60 / 60cm and are sold in packs of 200, but I want to bring up the price and if possible, sell in packs of 200 and 300 .
I create a product on which I added a personalized field "String" with cart option to define the size corresponding price here was good.
But I do not see how to packs, so multiply the price of the product chosen by the quantity of the pack.
Thanks for your help.
