This user is a scammer don't waste your time with him, just check his trust all the people he claims to have dealt with are know scammer and his alts.
Willing to use ESCROW.
If I'm not wrong skrill also can be reversed after the transaction completes so in this case, Escrow will be in trouble. No escrow will help you so if you want to buy BTC then you should use a payment method which is not a reversible method. You can just lock this thread for now until you find a good payment processor to buy.
