Detailed walkthrough
The quest begins by speaking to James Garrett. He is one of the Garret Twins, owners of the Atomic Wrangler in Freeside. Ask James if he has any work for you, and he will propose that you find him suitable escorts (prostitutes) for clientele with very specific interests. He has three unique requests: A ghoul dressed up in a cowboy suit, a smooth talker, and a robot.

The ghoul wearing a cowboy outfit is Beatrix Russell. She can be found at The Old Mormon Fort. Convincing her takes either a speech check or a barter check, otherwise you can bribe her with a bottle of absinthe. When she agrees you can either head to the Atomic Wrangler to get paid for the first escort, or find the other two first.

The smooth talker can be either Santiago, one of the dead beats Francine Garret hires you to find in the quest Debt Collector, or Old Ben, the chatty stranger standing outside the North Gates to the Strip. To recruit Santiago, just ask. For Old Ben, you'll need good charisma and high Speech skill. It is possible to get both smooth talkers to agree, however only one will give you the reward. If you chose Santiago AND Old Ben, Ben will show up at the Wrangler but you will receive no reward nor can you receive his services.

The robot is found at Cerulean Robotics. Cerulean Robotics can be a bit tricky to find if you are using the map-marker from the quest. Stay on the Old Mormon Fort side of Freeside. The trick is to continue west from the door that leads to Freeside (Silver Rush) right next to the Mick and Ralph Crier boy. Head northwest under the overpass and you'll come to some old train tracks. Head southwest along the street that runs parallel to the overpass until it bends around to the southeast where there is a Wolf's Bakery sign. Head south to the barrel with a fire in it (not the one to the southeast). The doorway is just a few steps to the east. There are a few Giant Rats inside, and the large assembly room contains a robot in stasis. The computer is an average hack (50 Science). There are also two pass keys to unlock the computer. One is behind an average lock on one of the cabinets in the assembly room, the other is on the floor in front of the television next to the decayed corpse. Once in the computer, you must upload an operating program.

To get a holotape program to upload to the robot, visit Ralph at Mick & Ralph's. He will mention the robot at Cerulean, and then will agree to write the program, telling you it will take a couple days. It took 24 game hours to be ready. Take the program back to Cerulean and upload it to the robot. It will power up and you will have a chance to test it out. The screen goes dark and you can hear a peculiar drilling sound. After the 'testing' has ended, your character experiences numbness, which 'is normal'. Whether you choose to test it or not, you inform the sexbot that its owner is James Garret and it heads to the Atomic Wrangler.

With all three escorts found, head back to speak to James about your pay. This will finish the quest.
