PROVEN MARKETING SYSTEM

[Martin CS]

As a real estate investor mostly specializing in wholesaling, I am searching for a proven marketing system and process that will allow me to run and manage my marketing operation like a true marketing department. 

Does anyone know of a system that's a proven marketing system for real estate investors or wholesalers?

To be clear, I'm not looking for a CRM or gimmicky system that does not contain all the components of a true marketing system from planning, execution, tracking, and calendar functions...to name a few. 

Thank you in advance!
