Hello
If you can provide 4 BTC and you accepte to use escrow here please pm me your rate.
Mate, deposit your money into poloniex/bittrex or any other exchange that have a low spread, even kraken is fine. If that is too difficult then use shapeshift/changelly as the guy above me said but changelly is known to hold up funds for a while before releasing citing numerous reasons and shapeshift rates are pretty bad compared to exchange rates on exchanges.
People here will only try to scam you. You'll be surprised at how little people will scam for, and even escrows can scam you as your amount is big enough for them to start to have malicious intentions(search master-p up, and he scammed for less $ amount than the amount you're dealing with right now).
