Make edits and re-design Shopify Product Page

Hi, i'm looking for someone to come on board who can re-design and amend my product page on Shopify

Previously messed around by designers who don't perform.

Please send examples of websites you've previously created

An example of the issue:
I have product variants - When you click on the product variants the image of the product should change to show how the product should look with the variants

I have the images, this shouldn't mess with the pricing

Adding text, and sorting out the layout

Easy to replicate for new listings
