Adding multiple variables (including quantity) affecting price

[Optic]

Hey folks,

Does anyone know how you can configure PS to allow multiple variables that affect price. Specifically I'm looking to have the price change based on product size (custom decals sizes such as 2X2, 2X4, 4X8, etc) as well as by the product quantity (without using the discount feature as quantities will be set such as 10, 50, 100, 200, 500, 1000, 1500, 2000). Essentially it'a two step process whereby price is set by size and then affected by quantity.

I do have Presto-changeo's Attribute Wizard Pro module installed.

Thanks!!!
