This organization offers a thank you program
when sending business to them:
I will offer a free foot massage session to people who get the word out about my Thai foot massage services. If you know anybody with foot pain, knee pain or athletes who want to recover faster and reduce injury risks, feel free to share my contact information with them.
Other health-related businesses can work on a mutually beneficial relationship with me where I would offer a special discount to their clients in exchange of a discount for their services to my clients.
