If you are not earning anything in your home country then come here dude.

You can initially come and live in a sharing room and try to look for a one bedroom flat in villa for 4000 and then also look for an oppurtunity for your wife here as ladies get jobs very easily then get your family here and then you can live happily. In worst case if you don't have any savings then send your family back and you can save....

You need to plan for all this. But basically 7000 QR is a good salary which you will not get in our home country.
