magento2 – Add extra price to the catalog – Magento 2.2

I have two requirements for this request to display an additional price in the shop window catalog grid.

One is to show an Inc. VAT, the other one (for another location) gives a price per square meter. I have given a very rough example below. I have created the attributes and be available on store front.

Enter the image description here

I'm not a seasoned Magento developer, but if I know which file I want to edit, I can change it in a design and have done so for other requirements.

I do not know if I misunderstood the terms, but I can not find guidance on how to do it nowhere. I was looking for!

If someone can help or point me in the right direction, I would be very grateful.

Many Thanks!
