I want to import a drone positioning system into my country and commercialize it. As an agent rather than the original tech inventor, how could I still make a profit once my competitors (bigger companies or my clients) start to import it without me or even clone the system themselves?
Ivan is spot-on with practical steps you can take.
I want to further explain this way of positioning. Find out right now - before the competition starts - what your competitive advantage will be. The personal experience, high quality customer services approach is the right one for a small business with large competitors.
Ask yourself what your customers need out of the experience and what they want; what are you, uniquely, positioned to give them, and focus on that in every interaction with your market.
