You Can Depend on Me

 is a quest in Fallout: New Vegas.

Quick walkthrough
It is given by Alice McLafferty at the Crimson Caravan camp. She tells you to deliver an invoice to Hildern at Camp McCarran. After which you are given three tasks to complete.

Detailed walkthrough
1. Simply deliver a parcel to Dr. Hildern. He can be found in Camp McCarran inside the airport on the first floor.

2. You need to buy out Rose of Sharon Cassidy's contract. There are a variety of skill checks that can be used such as barter and speech available to complete this. Once you do this she will sell her company, and in addition she will be available as a human companion.

3. You need to convince Jamison to quit his job. He can be found at the Atomic Wrangler Casino at a slot machine. He will quit his job without any checks but this will cause you to get only 300 caps from this mission, if you manage to make him quit using a speech check(over 50) you will earn 500 caps. If you have a high enough reputation with the NCR you can also gain access to another dialouge option to make him quit and you will receive the full 500 caps with no skill check needed.

4. (Optional) To acquire the Gun Runner's secret manufacturing specifications grab a Stealth boy and head the entrance of the Gun Runner's factory. Activate the Stealth boy and pick the lock at the gate, you will lose karma for doing this. Make sure are crouched and hidden. Head to the front door then all the way to the back of the building. Grab the information off the computer to the right of the room and head back out again. Make sure you are still crouching or else the guards will see you and attack. While crouched, if there are weapons on the workbenches, you can take them and the guards will not notice. Alternately, There is a shift change sometime between 10pm and 11pm (while the gun smiths are conveniently asleep) during which the player can follow a guard through the locked gate. The guard will leave the door unattended briefly to patrol the compound. By moving quickly and quietly, the building can be entered, the data retrieved, and the compound exited before the guard returns to his post.

4. (Optional) You can Deny the Gun Runner's section of this quest. You will still receive the experience, and completion of the mission. It will also allow you to continue onto the next quest that McLafferty offers you.

Bugs

 * If you have completed "There Stands the Grass" quest, Doctor Hildern might glitch and not accept your parcel.


 * If you are having Craig Boone as your companion, it would be ideal to have him wait outside when you're sneaking in as 4 out of 5 times he would attack the Gun Runner Smiths in melee mode when they go into his attack range, even if you're crouching and using a stealthboy. This might be triggered by you pickpocketing the smiths too. Thus jeopardizing your sneaking mission and you will be attacked by Isaac and the Gun Runner Guards upon leaving the factory. You will still be able to purchase from Vendortron though.
