eBay used to offer Trading Assistants but that program has been discontinued. Eventually, it was replaced by eBay Valet but that is only available for certain items in certain cities in the USA. If you have stuff you want someone else to sell, try creating a thread for it, or take out a classified ad. Or even search for that item on eBay and sort the results by Closest to Me and coldcall the sellers in your neighborhood to see if they want to do it. That's what I'd do.
