Cross Platform Listings 18 Products

I’m looking for a detail-oriented marketplace specialist to publish 18 products across Amazon, Walmart, Etsy and, if feasible, Bonanza. The catalogue breaks down into twelve graphic T-shirts, two paperback books, and three protein-boosting nut mixes.

Several of these SKUs are already live on at least one of the platforms; I’ll share the existing ASINs, images, bullet points and any template files. Your job is to reuse that material where it makes sense, then build out the missing listings so every item is represented on each marketplace with consistent branding and SEO-friendly wording.

Key deliverables
• Complete product detail pages on Amazon Seller Central, Walmart Seller Center, Etsy Shop Manager (and Bonanza if included)
• Parent-child variations set up for the shirts (size and colour)
• Correct ISBN data for the books and compliant nutrition panels for the snack mixes
• Optimised titles, backend keywords, bullets and descriptions tailored to each platform’s style guidelines
• Uploaded, marketplace-approved images—primary, lifestyle and infographics—sized per channel requirements

I’ll consider the project finished once all 18 SKUs are active, searchable and free of listing errors. If you’ve navigated flat files, attribute mapping or bulk upload sheets before, this should be straightforward. Let me know your experience with these tools and your estimated turnaround time.
