So I am needing a cart for a printing site and I want to know if Zen Cart can do what I am looking for rather than wasting time trying to figure out how to configure it, I thought I should ask this first.

Pricing needs to work like this.

500 Business cards for $50
1000 biz cards for $80
2500 biz cards for $120
5000 biz cards for $200 and so on

Can it be configured where I have a quantity pull down that is required of specified quantities of say 500 - 25,000 in like stages of 1,000 or so. And I need to be able to set the price for each stage of quantity invidually.

Also on top of this I will require attributes that effect the pricing based on quantity. Say that they pick double sided printing and it adds an increase of 35 dollars to every 1000 business cards.
