tiered pricing shown on product page

I have spent hours trying to find a solution.

I need to display tiered pricing on a new WP site, like I have on this 3rd party site:

https://cev.logoshop.com/ProductDetails/?productId=550794554

My demo site is: https://thebigrooster.com/product/beach-ball/

And as you can see, only ONE price appears.. How in the world can I get price breaks to appear? Also important, is each product we sell has a different minimum quantity. Can I make it so people cannot order less than a certain number?

please help!
