Luxury Travel Advisor

Hello! I have just become certified to be a luxury travel advisor, have found a host agency, and am ready to find clients! My niche is travelers who want authentic, one of a kind, epic vacations to Spain that are custom designed to their precise desires! I’m struggling with how I can deliver value up front, as the value I provide is in the execution of the planning, organizing, coordinating of the travel itself. Unsure how this particular market would respond to ‘freebies’, as they are higher income individuals (but perhaps even millionaires like getting free stuff?!). Unsure what kind of freebie would truly provide value. It’s very clear how to provide value up front as a coach, but not as clear in other industries. Do you have any ideas or resources that can help guide me?! Thank you very much!
