Should not be less than 10,000 QRs per month for 12 months (Summer should be included)

Benfits vary. But if you were sponsored by employer, should get housing, tickets and medical insurance, possibly kid(s) tuition or percentage of that.
And keep in mind that salary varies if you were employed by school or university. Usually universities should pay more.
