I personally would post the situation on the BOI. How much more proof do you need of a scam? Even if the 'cash' you sent is gone, he could PayPal you with a credit card. There are other ways of getting your money to you without him having to have the cash in hand. At the very least I would email him again and let him know that because you feel you have no other options left to you, you are considering posting on the BOI. That might light the fire under him needed to get your money back.
I'm sorry you had to go through that. I hope it works out for you.
