Just like the miniature model plane that can be scaled up, do what you are already doing. (I take it you are tracking), but scale it up.
It's important to track your operation. When you see what works for you, merely duplicate it many times more.
It sounds simple and it is. Evidently you have a successful small business.
What do you do when you're peddling slow on a bycycle and you want to go faster? Move your feet faster. Your legs will follow as you get more wind resistance. Put your gogles on and step it up.
It aint rocket science.
