Quest starts in Goodsprings Saloon, talk to the contract killer walking around the pool table. He has some work for you, the first couple of contracts are stealth based, where you have to be hidden while killing, or others will turn hostile. Voiced by me just for fun, so its pretty bad. However, its very easy to delete the voice folder, which is located in data/sound/voice, the folder to be deleted is ContractKiller.esp Save your game, post in comments if stuck.

This was originally made for a YouTube basic bounty type quest tutorial, and I kept on working on it because it was fun to make. The tutorial can be found below. An example .esp to go with the video can be downloaded from the optional section in files.
