WordPress E-Commerce Site Custom

I need an experienced WordPress specialist to turn my existing installation into a polished e-commerce showcase. The core objective is a fully functional product catalog: items must display cleanly, be filterable, and load quickly on both desktop and mobile. I already own the exact theme and design files, so the work centres on precise implementation rather than creative exploration.

Here is what I expect:
• Theme installation and configuration exactly to spec, including all demo imports or starter layouts required by the designer.
• Setup of WooCommerce (or another proven plugin if you prefer) with products, categories, attributes, and search / filter options matching the supplied mock-ups.
• Speed optimisation, image compression, and responsive checks so every product page scores well on Core Web Vitals.
• Basic SEO settings—clean permalinks, metadata fields ready, and schema for products activated.
• Final walk-through with me on how to add or edit products.

Please bring prior e-commerce catalog examples; a brief outline of the steps you will follow helps me gauge fit and timeline.
