Mass Quantity sales with discounted pricing

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.

Thought I would add this, I dont want it to show anywhere that it is a discount, cause its really not that is just what the price is for the higher quantities.

Also it has to show the price for what 500 cards would be total like 50 dollars not 10 cents per card.
