Is that all what they are offering you? I am sorry my dear but that is peanuts. Even for a single person to live here alone, he or she would require 7 to 8 thousand riyals per month if they are giving you accomodation or 12 to 15 thousand if accomodation not included in the package. Rents are disgustingly high and so are the food prices not to mention other living expenses. Please, don't even think of accepting that offer.
