WooCommerce 10k-Product Site Overhaul

I already run a WooCommerce store, but it needs a full tune-up before we scale to 5,000–10,000 products. Every key area—broken links, layout and visuals, site speed—must be fixed so the foundation is solid.

Once the clean-up is complete, I want the catalogue expanded and organized with intuitive product categories and robust filters that let shoppers dive straight to exactly what they need. The store also has to support multiple sub-domains (e.g. brand1.mysite.com) that resolve cleanly to pages I specify off the main site. You can visit the current site at www.hammertymehi.com to see what's going on. I also need the gallery with pictures of work like one main picture of after and when you click on it you can see before and pictures of progress it took to complete. I'm open to all new ideas. I have this started on siteground and can give access to whoever is chosen if you can work on that platform its integrated with wordpress.

Deliverables
• Repair all broken internal and external links
• Fresh, fully responsive design implemented in WooCommerce
• Performance optimisation (caching, image compression, code minification) until pages open quickly on mobile and desktop
• Bulk import/setup of 5k–10k products with well-structured categories & attribute-based filtering
• Sub-domain configuration and testing for seamless redirection/forwarding

I’ll provide existing site credentials, product data and hosting access. Please share relevant WooCommerce builds you’ve handled—especially high-SKU stores—along with your proposed timeline and any questions you need answered to get started.
