Good day,
I am an expert in elearning with over 20 years of experience. My experience includes but not limited to instructional design, course development, LMS's and many other advanced skills.
I have 8 years of advanced experience on Articulate Storyline up to version 3/360. I prefer to use Storyline over Rise as it provides more and professional options in addition that you could have the course in SCORM and can install it anywhere you like.
For the job you are asking to do, to be honest with you, this may need to go beyond the mentioned budget, actually the it first relies on the level of development you want. If you need it as a simple development level it will lower the cost, while if you need a high professional level it will increase it.
As you have more than 500 A4 pages, they will turn into 2000-2500 slides in addition to quizzes.
I can do the whole work, I have mentioned 60 days; it could be less, but I like to give more time for my clients so they check and quality assure every part of the development.
I hope to hear from you for further discussion, kindly review my profile which shows you some details about me and of course, I am ready to provide more about me and the course development along with related examples of my work.
Kindly initiate a discussion with me to continue.
Thanks and best regards,
