I don't know what is the usual salary for IT field and ur experience but I can assure u one thing. If u have a wife and maybe one pre-school kid, maybe u could manage to have a (very) modest life here with that money. For one bedroom apartment in Doha u will have to fork out at least 4K and the rest is barely enough for food, car installment, fuel, cell phone bill and such.
10K salary is the regulations minimum u need to have in order to bring ur family with u, so this also tells u something...
