Online school website and mobile app

Hello, we’re starting a school service very soon and for that, we need few developers to work on the Web-based platform and Android + IOS app

On the platform there will be teachers and students so basically it will become an ecosystem of students and teachers and the organizer (the school) will manage everything. also I’ll appreciate if you guide me on the branding/logo of the website.

Only bid if you are a company or have a team of individual developers for each technology, please explain to me in detail what you going to do, if possible give your links of the same kind of work.
