How can I create a custom 'About Us' page layout?

Hello, I would like to create a bespoke “About us” page with a layout similar to the below page.

https://www.dovemill.co.uk/pages/about-us

I want to have central text at top then an image on the left below/text to the right, then below text on the left/image on the right - then be able to repeat this for as many times as I wanted.

Can anyone help direct me to what code I need and where to add it?

Our existing Theme is Broadcast if that helps and this is our current “about us page” https://millysstores.myshopify.com/pages/about-us

Thank you

Tammy
