Create an accurate PSD file of my web page

I am looking for a series of web pages copying from online to a PSD version. I'm just looking for the first page to start with, and after this is completed perfect I will send across my further requirements.

I will need versions supplying in Desktop, Mobile and Tablet views for the page.

This is the first page - https://www.nonslipshop.co.uk/our-products/anti-slip-flooring-products/custom-sheets/
