Hey,
Firstly You should have applied for your SOWP with your husbands Study Permit. (They process SOWP faster that way,)
Anyways, I would suggest you apply for a Visit visa & try to apply for inland OWP. Visit Visa Processing time is 50Days, Whereas Outland OWP processing time is 43 Weeks.
If you get a visit visa & apply for OWP from there they do process applications faster.
There's very little information available SOWP & those who all go their visa's approved don't bother to respond to other applicants in these forums.
