In Saskatchewan, an aunt or uncle can sponsor you under PNP. If you look at their application guide at
http://www.saskimmigrationcanada.ca/appguide-family-members/ it says that "in-laws of the same relationship" can also sponsor so if you don't meet the requirements to be sponsored but your husband does, you can give it a try. If you are not sure, you can call SINP first. Their contact information is here:
