Two minutes is a gross overestimate. You can get it down to 30-60 seconds if you have an autodialer, but 90 seconds is a generous estimate even without. So figure 90 seconds per call, 30.42 calls per month per customer, you have 45 minutes per customer per month. $10 for 45 minutes is $13 per hour. $10 per hour labor (a generous rate for US-based English speaking labor) leaves a very thin margin, but still potentially profitable.
If you scaled this, you'd want to have a VoIP autodialer system, at which point you'd get down to maybe 60 seconds per call average, which is 30 minutes per customer per month, which is $20/hour revenue, so $10/hour labor would give you $10/hour on top of that to cover everything else. You could do this with call centers, which imposes real estate cost, or you could have a web-based system for employees to connect into from home, which also gives you the benefit of being able to hire them as independent contractors instead of employees and hence not having to worry about their taxes or health care.
There's further optimizations you could make. $10/hour is a high rate for paying people to place unwanted phone calls to complete strangers. I know because that's more than what I made doing that job. If you were running a call center of stoned teenagers and college students, you could probably get away with paying them $8/hour to call up subscribers and tell them they're awesome. Yes, most call centers are staffed by stoned teenagers and college students, at least the ones in charge of making scripted, outgoing calls. Well, at least mine was.
If you were running a call center of stoned teenagers
People only call centers staffed by stoned teenagers because they have to - they have an immediate problem they want help solving. Or they receive unwanted and unsolicited calls from them. Nobody is going to pay $10/month to receive a daily call from a stoned teenager who mispronounces their name.
I worked in one of those call centers, albeit not stoned, so I'm speaking from experience. Stoned teenagers are more than qualified to spend 30 seconds on the phone with you every day and tell you you're awesome. The quality control where I worked was quite good, especially with pronunciation issues. Calling a paying customer to tell them they're awesome is far, far, far less demanding than what we did where I worked.
