Wow, that is alot of money. Depending on where you stay as cost of renting an apartment varies on location and type. IF you get a room, sometimes it costs 2000~4000 for villa around old airport area. Those slightly better conditioned apartment flat like 2 bedroom ones maybe around 7500~13000 like holidayvilla service apartment. Water and Electric bill probably around 300 or less. Phone bill local is cheap+internet if you get a package maybe less than 500 per month (this includes the special TV package)

If you can secure an accomodation like now in some hotel cum apartments you might get a good deal for a period of a year rental as this is when less people visit Qatar.

Next is your transport. Assume you rent a car (think about buying later on), on average a decent car probably cost from 1600 to 2000. Fuel cost probably is around less than 200 per month if it is general travel within Doha to and from work with occassional travel in the weekend.

As for the rest, it depends on what you want. On average if you were to eat out generally and not fuzzy with food. Kebab, sandwich, occassinal macdonalds, daily breakfast cornflakes+milk+eggs+ham would cost you an average of 60 per person per day(pretty reasonable food). There is special permit to get if you wish to buy alcohol and only one place that you can purchase or drink at the 5 star hotels which costs alot more. Decent meal at a restuarant for 2 will cost from 150~500 for average ones. Expensive ones would be 1000 and above.

I hope this little info helps...
