QR3500 is enough for ur food.
if u want a 2 bedroom flat, u can have it for QR6000-8000
u may opt for a furnished accomodation
minimum charge for rent-a-car is QR100 (nice & clean car)

QR44000/month is a big amount of money here. a laborer gets QR500-700/month & their accomodation is like a small poultry (around 20 people in 1 room.

u r lucky that they offered u that amount.
