Help build course

I am writing courses. As an instructor it would be more efficient for me to have some TA's helping me write the course. For this project, I will pay $1 per hour of delivered content (video). Basically, I will provide you with notes and reading material. You must then go through the code, line by line, explaining everything and recording using screen recording software and a high quality microphone. There must be no background voice and a high quality mike must be used, as background sound is a unacceptable. I have to check all your videos before I pay you. You cannot have mistakes in the video because what you are delivering to me must be the final copy of the video which I will then share with my students. I prefer your voice is clear and without accent, american or british english. Each video must be broken up into parts as no video can be longer then 15 minutes. Each course should be about 20 to 30 hours long. I can pay you as soon as the video is checked by me for quality. I can pay for an unlimited number of courses. I ideally you can deliver at least one course per week of 20-30 hours.
