Fix Amazon Product Listings Setup

My Amazon seller account is fully registered, yet the products refuse to appear correctly on the marketplace. I only need focused help with the product-listing stage—nothing else.

Here’s what I’m looking for:
• Review my existing draft listings, identify the exact upload errors, and explain why the SKUs aren’t publishing.
• Guide me through—or directly handle—the correct upload workflow (flat file or web form) so each item goes live with accurate titles, bullet points, and images.
• Verify that parent-child variations, pricing, and inventory quantities display as intended.

This is a quick, low-scope task aimed at getting my first batch of items live. Clear, step-by-step instructions (or a brief screen-share) and confirmation that the listings are visible on Amazon will mark the job as complete.
