Looks like he is on LinkedIn if you want some more information about him.
If that is in fact the same guy, it's hard to believe that he would use his real name if he was intending to scam people all along. If I were him, I'd use a random name, like Nick Papagiorgio. Dunno - maybe something bad happened to OP (I hope not). But in any case, I hope the buyer gets this resolved. IF this was a scam, this is a BOLD move!!
