Hi, As a retired professor of Compsci, i am interested to do this content development for OS course. I have gone thru your requirements and syllabus.
However , you need video, ppt, notes and test questions. It is too small a price.
I can do ppt, video presentation and test for this price. Notes cost extra.
I have taught Os, Distributed Computing , Database tuning.... I am very very familiar with subject. Quality and originality assured.
