So am I correct in assuming that you're not going to post a picture of the device in question with your name and the date on a piece of paper ^[again]? If "yes", then the only way for such deals to be acceptable for a potential buyer is to be the one who'd cover the cost for an "escrow provider"!
^{- Nothing stops you from repeating what you already did in the past (wasting someone else's time and money [fee for the escrow provider])!}
