Build me a website and mobile application

Hi, myself Dr. Hitesh. I provide coaching to dentists who wants to pursue MDS (Master in Dental Surgery) by qualifying national level exams, for example, NEETMDS. I want to build a website and mobile application where I can provide online tests, video lectures, preparation notes with features like individual assessment of every test taken by students (who are already doctors), personal guidance and many more. I am providing a pdf to explain what I need in my website by taking examples from different websites.
