As the headline says, how about builing a company in which you hire students who are able to translate per skype for anybody around the world. Imagine a doctor cannot understand his foreign patient and he looks in the internet for a student who can simultanely translate the conversation.
The staff has an online table where you can book the person in a certain time. So they pay for the servive, the students get paid for it in a certain amount and the rest goes to you. So no risk. Furthermore the students can add hours when they got time and they are also learning. A win-win-win situation.
What do you mean?
