Once Niko completes his second Little Jacob mission, Jacob offers Niko regular work as a drug courier. Niko just needs to call Little Jacob whenever he wants some work. Jacob provides him with a location where the product should be delivered. The pick up spot is always a car parked near the Homebrew Cafe on the Broker-Dukes Expressway. The delivery locations are to numerous spots throughout Broker and Dukes. The deliveries are provided in random order.

After the completion of ten deliveries, Jacob texts that there will be no more deliveries because the cops are onto them. Completion of ten deliveries earns the Courier Service achievement. Your reward for earning this achievement is a Huntley Sport with a green flame paint job.

• Timed: The buyer is nervously waiting. Niko needs to get the deal completed within the allotted time frame.
• Stash: Niko must store the product in a secure location for a later pick up. Rival gangs usually know about the drop point and ambush Niko when making the drop, leading to a shootout. All of the rival gang members must be taken out to complete the mission.
• Deal: The deal is made in person without a time limit. Cops show up at the end of the deal. Niko must escape and lose his wanted level to complete the mission.
