Are you willing to let the escrow agent hold the bitcoin for 6 months, the time limit for submitting PayPal chargebacks?  If not then escrow is pointless, as are your responses.  You are sounding more and more like a scammer with every post.  If you aren't a scammer you would be offering TransferWise, wire transfers, or even Revolut, all of which are far safer for the seller than PayPutz.
