the offer on paper is good for a newbie teacher, but be very wary of Al Maha, they are run by the Talum Group who fire and dismiss teachers at will (mostly western teachers). The accomodation they will house you in is in a dive part of town, the building was supposed to be condemmed last year. The reason I know this is I have several friends who taught there, one still does and my wife teaches at the sister school Al Jazeera (also managed by Talum). Just do your homework on this school first. Good luck.
