I HEREBY SET A PRICE ON THEIR HEADS OF 1000 us $ A PIECE WHEN YOU CAN BRING THEM IN.
I WILL GIVE YOU MUCH MORE WHEN THEY R STILL ALIVE.
They stole a lot of money from me, about a million. 10 % who can bring them or track them down.
Lawful discussion aside, 1000USD per head is too few, that is 0.1% of a million. 10% is more justified, that is 100,000USD, so that two heads fetches a house. You also need to be explicit about "MUCH MORE" because contract killing nowadays barely work even on explicit promises. Your best bet is that the pay is so high, that some began to consider it, then the money returns to you from whoever wants to live - a happy ending that on one has to die:)
