E-learning Platform Content Enrichment + Marketing

I'm looking for someone to assist in enriching the educational content on an already established e-learning platform. The primary focus of this project will be enhancing the existing content, optimising it for a better learning experience and potentially adding new material. In addition to this, I will also need help marketing the e-learning platform.

Key Requirements:
- Enhancing the existing educational content
- Potentially adding new material
- Ensuring the content is engaging and effective for learning purposes
- Experience in marketing an e-learning platform or a similar educational product would be highly valuable

Please note that the target age group for this content was not specified. Therefore, you should be able to adapt the content to suit different age groups, whether that be children, teenagers or adults. Experience in designing for different age groups would be a plus.

Please provide examples of similar projects you've worked on, your approach to enhancing educational content, and any marketing strategies you've successfully applied in the past.
