I have a website based on academy theme by themeforest (http://themeforest.net/item/academy-learning-management-theme/4169073). This is a good Learning Management System as long as there is only one instructor. I want to allow more instructors to prepare courses and lessons and they will manage their courses. I want to create an interface where instructors are not able to access WordPress dashboard but Still able to create courses and lessons. Each lesson will allow instructors to upload pictures (all image format), document (pdf, doc etc), and videos without accessing WordPress dashboard. Interface should be very user-friendly. Only experienced WordPress developer should bid on this project.
