Good day,
I am an expert in elearning with over 18 years of advanced experience that includes but not limited to instructional design, course development, writing, training, LMS's and many other areas.
This is not a final bid as there would be a need to provide more details in order to estimate the size of the course.
As I do understand from your description that you are mainly in need of course writing/rewriting based on the material you have, after writing the course material it needs instructional design which means making the content suitable for a training course, then you may/may not need course development in order to make it usable as an elearning course on any suitable platform including the internet.
If the 3 stages of developing a course into a digital format is required, then this will make the job larger and in need of specialization to make it work well, therefor this increases the cost of the course. This may exceed USD 2000 to make it full.
So, basically provide me with more details or chat with me, I will try to help you as much as possible. By the end, I can provide you the course as an elearning course that can be accessible through the internet.
Awaiting you reply.
Best regards,
