Shopify Template Product Page Customisation

UK based jewellery and accessory e-commerce website requires minor customisation.
The website is fully functional and live; however I would like the Product Page of the Material Shopify Theme customised in a slightly different format; please therefore refer to the attached document.

The existing theme can be found here: https://rt-material2.myshopify.com/collections/clothing/products/accusamus-et-iusto?variant=4107271044


Thanks in advance
