I am an Online Computer Science Tutor. I need some freelancer to generate leads i.e. get students who need online tutoring in Computer Science (IB, IGCSE, AP). I usually charge 15$per hour from students. The amount which I am planning to pay would be 10$ per student if the student takes less than 10 hours, and if the student plans to take more than 10 classes, then 15$ for every 10 classes he take.
