Sorry to say but you might have to trust an "expert" with the file, and to trust that he.she wouldnt run away with the money. After all, it would be a crime and who would commit a crime for a louse, lets say, 10 BTC, 140K dollars? Not worth the bad karma

I indeed believe in the concept of karma, so I would get it back in some way anyhow. But i would prefer to have the coins in this life
