I am developing a website that connects a set of tutors and a set of students. The students log in, they look for the type of tutor they need, then they can see the schedule available for the tutor, and request an appointment. The tutor is notified of a new reservation, then logs into the system and accepts the appointment. The student is sent notification for payment, proceeds through payment, and receives confirmation. How can I build this with Joomla?
