I am a postgraduate in Economics and by delivering lectures I can earn $5 to $10 per every 2 hours. In myLot, I may be earning 1.5$ per hour. If I can do speed typing to answer the discussions with meaningful discussion, I should be doing 2$ per hour.
One $ per hour should be OK. If one is efficient, one can earn 2$ per hour. If you are software expert, may be one can earn 10 to 15$ per hour. This is approximation and it may be less or more.
