The mobile app will require a user sign in with a predefined application form (name, email, phone, profession, address...). The landing page will include a message box (check attached draft) where users will submit their request in text which should be received by the administrators to be processed, afterward admins will communicate with the user using a build-in messaging system. Chatting system will be very basic, only text. Chatting history should be available offline. In the left menu, it will be available only browsing pages (info, contact, FAQ...) .
