Since pros pay for leads, shouldn't customers pay for inquiries, conversations, or communication with pros? This way it is a balanced and most importantly- FAIR way to allow communication to have integrity between pros and customers.
1. Customer pays $5 for inquiries.
2. Then Pros pay $5 for the lead above.
This creates a balanced, fair, and healthy connection between all parties involved where it reduces the amount of "ghosting" and makes the lead more serious.
