You will have to set up a listing for him.
Use his eBay ID as the title. Otherwise picture and describe the item as you would normally.
If you are eligible for the 50 Free auction listings, use one of those since it will be cheapest. Don’t bother with any of the bells and whistles eBay sells you; none are worth the money normally, and you have an almost guaranteed customer.
Make the opening bid the agreed price.
Then tell your customer to search for his own name and bid. Give him a short deadline (48 to 72 hours). When he bids, end the auction, and he will be the automatic winner at the opening bid. (Which was the agreed price, remember? This is important!)
Now eBay can see the sale, charge you your fees and cover the customer with their Buyer Protection.
If the customer does not pay in the agreed period, add him to your Blocked Bidder List as a time-waster. Use the Revise Listing system to change the title to something more saleable than his name and adjust the asking price (if you want to.)
Since most bids come within the last few hours of an auction, you probably have not lost any customers with this backup strategy.
