Hello,
I have over 14 years of experience in Educational Technology and elearning.
I am an expert in elearning systems and development including instructional design.
Of course this is not a bid, rather it is a communication area for brainstorming.
I do not have the courses you need ready, but I can help in either or both of 2 ways, guiding you to where are good resources are or developing such courses for you. Please note that good resources that you may buy to re-sell would cost $2000 upward, this may not include editing features, they consider this cost as they sell many times and rent it for users.
For some of the courses below, I have the experience like photography, MS Office, Photoshop, the latest 2 which I have been a trainer for many years.
Of course, courses, may not only be as videos, but full interactive giving the user full engagement and effectiveness during the course that may also include quizzes.
Preparing such courses lead to another question; how they are presented? And, how they are sold? Answering this question will mean involving the creating of an LMS to host courses, manage users, payments, trainers if any and so on.
If you like to continue, please let me know by PM so we could discuss further.
Best regards,
