A new way to cargo industry? While there is almost no company that is thinking about it? I think that there is a must to congratulate you because what you have found as an idea will make everything in that sector easier than it usually is. It is, of course, sure that we need more information since you mention SKYF(unmanned aerial carrier), which means that I have never seen something like this. Your tokens are really enough, not little; your operation steps are acceptable because it is with logistics providers, which makes me feel at safe. So, everything seems good!
