I think that's the difference in terminology between "mentor" and "tutor."
With "tutor" it's clear that you are going to be paying for tutelage.
A mentorship is supposed to be an ongoing relationship with a single individual that is not necessarily fee-based --someone you just have a chat with and get advice from.
This seems less like a mentor site and more like either a tutor site or a contractor site where you are getting contracted help on problems or understanding.
