@Zubair. This is the only recognized consultant I can recommend you. They have offices in khi, Islamabad and Lahore. You can meet them in person and discuss your case. They are also a representative of good Canadian universities they will help you out with course selection, admission process and visa documentation. http://www.rmt.com.pk . You can also check out websites of these listed universities if they are registered with them as agents/representatives.
