Woocommerce pricing table based on qty

Hi, i am sure there is an easy solution or an extension for my problem but i dont know what to search for:
I sell prints. For example brochures or business cards,
The price is based on minimum order of 1000 pcs and it decreases as the quantity increases.
Lets say 1000 brochures cost $1 each but if you order 2000 pcs, it would cost 0.7$ each and so on.
Something like this site:

I hope u can help me.

Right now i am using variables and attributes but it looks ugly and tedious to update.`
