like already said by others, as soon as your husbands resident permit is done, he can get your visa within a week ( like I did). But this will need strong desire from his company and is definitely possible as his salary is above QR 4000. But let him make this part of the deal before he gets here.worse come to worse, he can get you a visit visa and bring you here very soon.
Regarding your job, I think you can get a job here easily, there are a lot of new openings here. Go to www.gulf-times.com to see the classifeds here already and you can start applying even before you get here!! Good luck.
