If you are really sure about what you are saying, we can meet. I know someone who can make this transaction in Dubai but about 100 - 500 coins a day until we reach the amount of bitcoins you need. But it's never going to be -4%, most probably -2%. But we can talk.  

Transaction will be made in a office with both buyer and seller on desk, this company will do the escrow service for both "you and seller". This company has done many transactions before, so trusting them for escrow is 100% reliable.
