Tweaking woocommerce plugin

I am using woocommerce product list pro plugin on this page. I want to modify a few things here. I want to set minimum cart value to 2000 if the order is being placed through this tablet made by plugin woocommerce product list pro.

Another problem is here in this image: https://imgur.com/a/ZTimS

As you will see the filter button is overlapping the search box and reset button is just like a text, not like a button. This table and these features are part of woocommerce product list pro plugin. I want that fiter button should not overlap the search box and Reset link should be like a button as fiter.

How can I achieve this?
