Question
It seems like it does have potential considering I could hire an agency outside the us for $4 per hour and they could reach a lot of customers in a short amount of time. The problem is that people don't like telemarketers in the first place, so it could have negative effects.
The type of business is food delivery from restaurant's.
Answer
Telemarketing consumers is risky today, especially with do not dial lists. A more cost effective solution is couponbooks/direct mail, unaddressed bulk post mail within specific postal code/zip codes and inserts/flyers at the restaurants themselves. At $4/hr (usually offshore call centres), you need to make sure they are calling at the right times to avoid iritating customers.
