Okay, I have students who have balances in their Preply accounts. They are corporate students, meaning that their lessons were paid for by a company. Since they have just completed their exams, they can't ask for a refund because if they do so, the funds will go to the company that paid for them. That's why they want to schedule lessons with a tutor and cash out. I hope you understand.
50% will go to the student and then we share the rest 50/50. We can have as many lessons as you can handle daily. Preferably at least 5 lessons.
You will have to raise your price per lesson to 40 USD.
During the trial lesson you can just play an educational video and share your screen. Just for 25 minutes.
For ease of withdrawal and transfer, You will withdraw only our share using a PayPal account that I will give you then you withdraw your share using any of your suitable methods.
We will withdraw after every lesson so that the student can see progress. 
Try to be as available as possible in order to maximise.
