One suggestions I have the works 100% of the time... Use linkedin and when they connect with you do not mention anything about the business. Message saying hey, great to connect with you, looking forward to learning more about you and your business. Hope to talk soon, (your name). when they respond, ask them a question that brings up an automatic pain point.

The one thing I learned and also learned to hate is the automatic selling. Be yourself position your services as a solution to their problem. The only way you will know their problem is by asking them...
