Good day,
Thanks for offering this project. I am interested in it. This is not a bid but a way to communicate and explore the needs & requirements.
I am an expert in elearning with over 17 years of experience including LMS advanced experience.
Moodle is no question is a one of the best free source LMS's it is mainly free as a code, but of course not free as development.
Moodle can handle the number of students and other users you mentioned and even more if it is installed and configured correctly to serve this number of users.
Although Moodle is a good and reliable system, I could not find out how you intend to use it in order to advise you, are you going to upload materials for online learning, or actually mange courses for face to face classes, if this is the case, I should suggest alternatives to Moodle.
In such a system you should expect the cost will be starting from $1500 upwards in order to provide you with a good and reliable system to handle the number of users effectively.
Kindly review my profile then let's have a chat.
Best regards,
