2. You listed 2 data scientists in your team - I know Machine Learning is something not everyone can grasp. Are those people qualified? What Machine Learning projects they were part of? What courses they graduated?
Yes, we are qualified enough 
I have about 3 years of experience in the area of Data Science, Machine Learning and Computer Vision. I'm PhD in Applied Mathematics and an Associate Professor of the Mathematics, Mechanics and Computer Science Institute at the Southern Federal University. I studied cs231n and Coursera Data Science course from Moscow Institute of Physics and Technology. Projects from previous job are part of NDA and cann't be shown. Current project is ukit AI.One more our team member successfully won Apple WWDC Scholarship due to her Machine Learning project. She is also finished Introduction to ML course from Moscow Institute of Physics and Technology about 2 years ago and applied for Andrew Ng course and cs231n.
