Change to Moodle LMS sign up page, User Role and user desktop

This is what we need to carry out: add a field to the sign up page/database ( teacher or student) homepage/login/[login to view URL] give user role (student or teacher) to the user based on their sign up choice ( teacher or student) add a user role search field to the admin panel homepage/admin/[login to view URL] to search students and teacher ( similar search exists for system roles and course roles) redirect users after sign in based on their role to two different pages. at the moment they are redirect to a common page( My Moodle Page), we want to make a copy of this single page, change their names and redirect user to them properly. replace the access to these two pages with the single page in the admin panel. homepage/admin/[login to view URL]
