I need an exact copy of a landing page made on squarespace

My client is a creative agency: www.goldiecreative.com (password = emily)

I have set them up on squarespace with a domain and email addresses, plus a basic repeat pattern holding page.

But we would like to replicate this website's holding page: https://juliasarr-jamois.com/

We can provide the logo and a similar white background image with their project imagery on.

They want the same horizontal and vertical parallax functionality for both mobile and desktop.

This needs to be coded / created using squarespace platform if possible.
