WordPress/WooCommerce Website Fixes + Product Page Simplification -- 2

I have a WordPress + WooCommerce site selling fish food products (6 SKUs). I need:
✔ Cleanup and simplify the homepage design — professional, clear branding, readable fonts.
✔ Improve product pages: larger images, clearer descriptions, readable text, strong “Add to Cart” buttons.
✔ Add few page, blog section, connect via WhatsApp, social media links.
✔ Upload product images & update descriptions as provided.
✔ Ensure mobile-friendly layout.
✔ Configure basic SEO and site speed optimization.
✔ Add newsletter signup & social proof/reviews if possible.
Simple white website with a big prominent place for my logo. I want simplicity to be maintained.
