Price impact on article attribitions and discount prices

[pbrakkkkee]

Hi everyone,

I hope someone can help me. I'm setting up a Prestashop at the moment for a printing company with a lot of different products. One of them are flags. They have a few different sizes and when you order more than 5 products the product get's cheaper.

I want the customer to order this flags in steps.

- Step 1: choose your quantity
- Step 2: choose material
- Step 3: choose your size (one option)
- Step 4: choose to add some extra infomation (a few product attributes, multiple options)

All these options change the price of the flag. And I want to change the price even more when the customer orders more than five items.

Is there an module for this? And even better is there a module who does this and also can calculate the price om square meters and has discount prices on sqaure meters (besides flags they also sell banners etc.)
