Greeting from Lucent Innovation...!!!
Hello there,
I am shopify expert here.
I have list of reference website, I had work.
I feel, shopify don't have support to add multiple variant, so you have two option
1. Install bold apps ( $9 - $19/month)
2. Custom app development
My bid is almost much down end, but We have a great experience in theme development, in theme customization, Shopify app development.
We have two published & approved public app in shopify app store.
We are looking to have a great discussion
Thanks, Nitesh
