Easy 1000 Dollars
Once you get to the "Poppycock" mission in Mexico, you have to find a package, deliver it to someone, receive $1000, then give the money back to the seller of the package you delivered.
Of course, you can just not complete the mission after receiving the money, but for an outfit, you must complete the mission. Return to the seller and return the money. Wait for him to go outside, then point a gun at him. He will start shooting at you. Don't do anything or else you will have a bounty on your head! Let the police shoot and kill him. Then, loot his body and you will get the 1000 dollars back AND mission complete!
