Unusual question about middlemen/paypal/etc

So I listed my LoL account on Ebay and have a buyer that only has a Korean bank account, but lives in the US. He wants to go through a 3rd party site to buy on Ebay because it gives him certain benefits and it's already linked, etc etc.
What I want to do is get a middleman, send the buyer something tangible(like a crude drawing or some shit) overnight, have him send the middleman video proof of him opening it. I also want to send the middleman the price of the account to hold, and once the payment clears and email listing is closed, feedback left, etc. Then the middleman will send me my money and the ebay situation should be all set, right?
Or is this totally some sort of scam I have no idea about?

 

If it sounds fishy, it's probably a scam. I'd probably look for another buyer. Middleman's won't hold any type of money that is reversible such as paypal, skrill, etc (so they won't be financially burdened by any chargebacks/disputes). In addition, many MMs won't deal with IRL trades, due to processing and handling fees, along with many other complications. That being said, you'd be hard pressed to make that deal happen safely.

 

Well that's the thing, I wanted to find a very trusted middleman and send him(if need be through a non reversible method) the money in the amount of the auction to hold, and have the buyer proceed with the auction as he would normally, mark the item as recieved, leave feedback, basically seal the deal there. Then the mm would give the info and once he clears that send the money back. Or can people charge back after it's marked as received?
