I am in the process of creating an eLearning platform for students who can teach each other. More specifically I want to build this platform: https://vimeo.com/1143136495

The platform is based on the following API: https://tokbox.com

My question is what type of Developer can build this? The process to build it should not take more than 5 months.
- Can a student developer build this or should it be an professional?
- Also, is it enough with one developer or do I need more to build it in less than 5 months?
- What specific skills should I look for when hiring a developer who can build it?

I am looking very much forward to hear from you! If you would be interested in building it with me please let me know!
