Dear teachers,

Would you been kind enough to share with me your opinion concerning the following sentences?

Need he have left?

Thanks for your efforts.

Two additional notes:
The third one would be very uncommon in the US, and the fourth one doesn't have the same meaning (but you probably knew that).
