Integrate Jewelry Store into WordPress

I already run my main site on WordPress with WooCommerce and now need a seamless expansion: a full body-piercing jewelry store woven into the existing structure, not spun off as a separate shop.

Here is what I need done:
• Product catalog and search – thousands of barbells, rings and after-care items must appear in a clean, filterable catalog that feels native to my current theme, complete with advanced search and attribute filters (gauge, metal, length, colour).
• Inventory management – every SKU must sync correctly with WooCommerce stock levels so I can track back-orders, low-stock alerts and bulk updates from CSV without breaking anything elsewhere on the site.

All design work should respect my current branding; I do not want visitors to feel they have left the site when they browse jewelry. If custom templates or hooks are required, please build them in a child theme so future updates remain painless.

Please outline how you will:
– import or create the product taxonomy,
– implement the search and filter logic (mention any plugins or custom code you favour),
– handle inventory sync and bulk edits,
– test to be sure the checkout flow, coupons and reporting stay intact.

I will supply sample product data and admin access as soon as we agree on the approach.
