According to the rules of the immigration authority in the country the only way to have your family visa for visiting or living here with you is:

1.- You "MUST" have RP not visa.
2.- Your monthly salary must comply with the minimu limit set by the authorities to bring in your family. (I guess nowadays it is 7000 QAR/mo)
3.- In case you have RP then you must get a NOC from your Company so that you can sponsor your family/wife/kids.

Maybe a Hotel can help you, maybe. Do a search...this topic has several discussions in the site.

Regards!!
