Hello
I can see you need need someone to say how can you create product variants through Metafields to show the customer each variant on a detailed product page.
I have a good hand in Shopify, Theme customization, Theme Installation, App Installation, Site Design & Layout and Payment Gateway Setup.
I will make a smooth workflow and keep you updated with work progress.
Please message me through the chat box to discuss this project.
Thanks
Regards,
Azhar
