Software Developer: eBay Seller Integration

I'm looking for a software developer who has experience with eBay seller APIs (creating/updating listings)

I have a Google Sheet which contains all information required to create an eBay listing (including the Item Description HTML)

I need a way to update all eBay listings in or eBay store based in the data in this spreadsheet.

My preference for language would be either NodeJs, C# or PHP, but happy to consider whatever you'd recommend.

If you could also please include how much you charge per hour in your application.
