Interactive Learning Platform for Teens

I am looking for a developer or small team to help build an interactive online learning platform for Bedmas Academy, a tutoring company focused on math education. The platform should be inspired by the style of Brilliant.org, but customized for our own tutoring program... (Budget: $750 - $1500 USD, Jobs: Database Design, Django, Frontend Development, JavaScript, Mobile App Development, Python, UI / User Interface, User Experience Research, User Interface / IA, Website Design)
