Shopify Web Developer - Needed ASAP

I need someone to undertake some work on our website with a quick turn-around.

Please message me with your feedback to the document attached.

Only message me with direct feedback and not a generic, I can do it. I need someone to show they can do it.

This is what I need:

1. Add reviews onto all product listings, based on adding an app I installed. Or find an app that is better.

2. Add colour chart to each of our listings for stock and bespoke hair systems.

This is our website: https://buyhairsystemsonline.com/

Please message me so that I can share what I am looking for with the apps on our website.
