Modding Request: Charge Simoleons for Conducting a Seance

Greetings! I'm interested in my Medium Sim making money by offering to conduct seances for other Sims. Specifically, I want the "Commune With The Departed" interaction on the seance table to have the option of picking a Sim or Sims that will pay for the service and earning $200 a pop. 

Thank you for any interest in this modding request! I'm happy to answer any questions about what I'm envisioning if it's helpful. Have a great day!
