Shopify & eBay Integration Expert Needed – Inventory Sync with Independent Shopify Pricing

I have an existing Shopify store and an eBay store with approximately 200–300 active products. My Shopify website currently redirects customers to my eBay listings because I have not yet found a suitable integration. I am looking for someone to configure my stores so that: * My eBay products are available for purchase directly on Shopify. * Inventory is synchronised automatically between Shopify and eBay. * New products added to eBay can also be added to Shopify. * Shopify and eBay prices remain completely independent. I want my Shopify prices to be different than my eBay prices, and I need to be able to update Shopify prices in bulk (for example, applying a percentage discount across all products or selected collections) without those changes ever updating my eBay prices. What I’m Looking For Please only apply if you have experience with Shopify and eBay integrations. In your proposal, please answer the following: 1. Have you completed a similar Shopify/eBay integration before? 2. How would you achieve the requirements above? 3. Would you recommend an existing app or a custom integration? 4. What would your estimated cost and timeframe be? 5. Can you provide an example of a similar project you have completed? My budget is flexible for the right solution and expertise. I am looking for a reliable long-term solution that can scale as my product catalogue grows.
