You can surely come through the "visa on arrival" system but your stay will be limited to just two months maximum (1 month plus an extension of 1 month). While here, you can look around for a job but jobs are not very easy to get here. The competition is tough.
Then also, your husband cannot get a permanent family visa due to his salary level. The minimum salary requirement for such a visa to get approved I believe is QR 10,000. That could be of disadvantage to you.
You should keep these in mind before you plan your trip.
