Alright, I'm not sure if this works with both Male and Female, but my character is Male so it worked fine. North of the "Sunset Sarsaparilla Headquarters" and slightly NW of "South Cistern"(if you have found it) there is a place called "The Thorn". It is actually in a sewer, with many "Westside Residents" roaming the topside of it. Enter there, and there will be a women with red haired standing over the arena(you can also fight creatures here for caps), go talk to her and ask if she needs any help. She will say she needs Giant Mantis Eggs, and give you the quest "Bleed Me Dry". Once done, she will ask you for Radscorpion Eggs, then Fire Gecko Eggs, then Night Stalker Eggs, then Cazador Eggs and finally, Deathclaw Eggs. She will give you the place to go, so there is no need to worry, just have Boone with you, as his sniper will greatly help you. A tip, whenever you're doing the Deathclaw one, before entering the place, crouch down and once entered, activate a Stealthboy, you will be able to get the eggs and make it out without having to fight any of them, as they will probably destroy you(I'm level 25 and had a hard time with 2 at the entrance, imagine 3+...). Also, your companions wont affect you as the Deathclaws will not attack them so long as you have the Stealthboy activated and are sneaking. FYI, my sneak level is 16, so it matters not. I wont spoiler how exactly it happens, but the way to start it is kinda stupid, but the resulting product somewhat makes up for it, just remember to have your volume at a decent level
