babybluz, keep applying to all jobs that suit your category, on Bayt.com and other job sites catering to Qatar. Don't focus on Pakistani schools only. Widen your search and make a good, comprehensive CV, and start applying with a convincing cover letter ready.
Most schools bear expenses and sponsor visa. You and your husband should take the plunge, be well prepared; as in your resumes' should be precise in details. Your experience sounds good. Wish you the very best :)
