How to create special business model ?

Hi,

I am working at consulting company and today I get new task to do. Unfortunately I really don’t know how. Please help ;) I haven't got a lot of business experience.



So, my boss has a foundation which organize once a year a charity big run for other companies. He has got list of 500 companies and they enjoy the run. All the increase money are transfer to local hospital. People really engage with this event.



Soon he is going to open new business like: “Challenge your company”. All the companies staff will be challenge another department (inside). Also it is possible to challenge other company (outside). I must create 2 things:

- Value of join to the program,

And

- Business Model (how to earn money, who will pay for that)

Please help



Best wishes ;)
