Hello,
I am an expert in elearning systems and development with over 13 years of experience and would be happy to work on this project.
I can the changes and customization you need, but I work on flat rate, if this satisfactory I'd request about $100, while for the course $500, I can do the course for you in Moodle directly as a Moodle based course or as a SCORM based which can be imported into Moodle, the SCORM may provide extra features like communicating with Moodle, animations, video, with full interactivity navigation.
Please send me a PM here to enable further communication.
Best regards,
