Quick walkthrough

Unmarked Quest: Strictly Profitable 
Talk to Grouse and acquire the Mesmetron
Fire the Mesmetron at an NPC to stun them. 
Talk to them and put the slave collar on their neck. 
Tell them to go to Paradise Falls
Return to Grouse. 
Reward: 250 Caps 

Detailed walkthrough

After receiving the Mesmetron from Grouse in Paradise Falls, one has the option of enslaving non-player characters other than the four VIPs required to complete the quest Strictly Business. For every slave that is captured and sent back to Paradise Falls, Grouse will pay out 250 caps, and will hand over a new slave collar to continue the "recruiting." He also sells Mesmetron power cells at the steep price of 200 caps per 10 rounds. It is possible to offset the high price if all 50 rounds he initially gives out are carefully utilized, since he also pays out caps for turning in the VIPs.

Rewards

250 caps are rewarded per slave.

    If you agree to Grouse’s request for slave collecting and bring back all the slaves he requested, you can continue this plan indefinitely, forcing a Wastelander or other amenable person to flee from you in combat. Then, zap them with the Mesmetron and snap a Slave Collar around their necks. Accompany them or instruct them to head to Paradise Falls. You are awarded 250 Caps for each additional slave you bring back to Grouse.
