Ok, if I put the 1 BTC on escrow, and after making sure that your wallet indeed have the 12 BTC that you say; then escrow will release the 1 BTC to you, deal?

How do you make sure they dont spend the 12 BTC after 1 BTC was released by escrow?

I will only be sure after I open the wallet and transfer the BTC to my wallet
I don't know what mean Escrow and don't understand what you say?
What I want is : You send me 1 BTC and I will send you wallet.dat , where located 12 BTC and also all I know about that encrypted password. For me was costing this 12 BTC only $ 60, so I will have profit already if you send me 1 btc. So lets do it! This is win win situation.
