Ezdan in Wukair is going to be a bit out of the city and it will take you much travelling time to get to office and back. Suggest, you search for something in the city. Qatar Living has a section "Properties" which you can scroll through for some information. As for the cost, it varies from area to area and accommodation to accommodation. I guess you should be able to find one around QR 4000 per month with electricity and water supply. Suggest, you select one after you land here.
