I need 10,000 home-appliance items from several brands loaded into my Magento backend in a single, clean import. Every SKU already has a matching PDF product manual that must appear in the “Downloads” tab of the product page. All items form part of larger configurable sets, so each one has size, color, and feature variations that need to be combined correctly. While you prepare the CSV (or use any other bulk-import method you prefer), please also link appropriate related products so cross-selling works out of the box. Deadline is 3 days from project start, so accuracy and speed are equally important. The catalogue will be considered complete when: • All 10,000 simple SKUs plus their configurable parents are visible in the admin and on the storefront • Size, color, and feature options switch smoothly on the front end • PDF product manuals download without error and are mapped to the right products • Related-product blocks show at least three relevant items per page • No broken images, missing attributes, or duplicate URLs appear in Magento’s reports If you already work with Magento’s Data Import, CSV, or third-party tools such as Magmi or FireBear Import/Export, that experience will be useful here.
