Spouse and parent sponsorship from UK

Hi I was hoping someone would be able to help.
We are looking to move to Nova Scotia, Canada this year. I am a Canadian citizen by decent. My husband of 9 years is a British citizen and UK trained nurse. My mother in law is also hoping to move with us, she is 50 with no skills. We also have a 2 year old daughter
My questions are:
If I sponsored my husband and daughter through the family sponsor scheme would this, then prevent me sponsoring my mother in law when we get there? (as I understand I can’t apply for parent sponsorship until I live in Canada).
Do I have to submit the sponsorship for my daughter at the same time as my husbands? And how does she then get citizenship (this bit really confused me as she is my dependant therefore can come anyway??)
Would it be easier/ cause less problems to use Express Entry for my husband as he is a nurse or is family sponsorship the way forward?
Has anyone sponsored a parent (in law) into Canada? I understand the wait is 5 years currently but is there any way around this/ to accelerate the process so that she can still work rather than on a parent visa?
Any help/ guidance is appreciated. We were using an immigration specialist to help but unfortunately they went bankrupt and took all our £2000 fee without any help last year so we are trying to do it all ourselves
