Shopify Collection & Customization Setup

I already have the product photos and copy in hand—I simply need someone to get them live. There are 13 products in total, several with the usual size-and-colour variants.

For a handful of those items I also want shoppers to decide whether they’d like customization. When they tick “Customization – Yes,” a single-line text box should slide into view so they can type the name they want. If they leave the box unticked, nothing extra shows. Choosing “Yes” must automatically add the specified surcharge to the cart. A live or static preview isn’t necessary.

Please create the collection, add each product with its variants, wire up the custom-charge logic (a theme edit, Shopify Scripts/Functions or an app—whichever is cleanest), and confirm the flow works from product page through to checkout.

Deliverables:
• All 13 products uploaded with correct variants, pricing and images
• Customization toggle and text field functioning only on the specified products
• Automatic surcharge applied when customization is selected
• New collection published and tested end-to-end

Once everything is in place and tested, let me know so I can do a final review and push it live.
