Hi,
You can post your resumes in Dohacareers.com - Qatar's premium and affordable job portal covering jobs from all sectors and industries in Qatar and the Gulf region.

Since It concentrates more on doha qatar area, i think this will relly help you in getting a job.
The other site is www.egulfcareers.com.

I found both of these sites really effective & got a call within a week of my job posting...,
I think that it will really help you..smileys with beer

Besides this you can post in other job sites too,but their response has gone down these days..
