1. Set an expectation for hours and days worked. Be sure to set a realistic expectation for the number of hours your cold caller will work each week. Too often, business owners try to skimp on this expense by hiring someone part-time or with too few hours to truly be effective.

2. Pay per results. While it may seem like a good idea to pay your cold caller a salary, this could actually work against you. If you don't see results, you're essentially paying someone for nothing. Instead, offer commissions or bonuses based on results achieved. This will incentivize your cold caller to produce results and give you a better return on investment.

3. Hire someone with experience. This may seem like a no-brainer, but it's worth repeating. Hiring an experienced cold caller will pay off in the long run. They'll be able to hit the ground running and start generating results quickly.

4. Provide adequate training. Even the most experienced cold caller will need some training on your specific product or service. Be sure to give them all the information they need to be successful.

5. Have realistic expectations. Don't expect miracles from your cold caller. They can only do so much. If you set unrealistic goals, you'll only end up disappointed.
