You haven't provided very much information so it's a bit difficult to guess what you are asking.
If your husband already has a full time job offer and an approved LMIA, then he can apply for the work permit on his own and there's really no point using a consultant. If your husband doesn't yet have a job offer or approved LMIA, then I would find a job offer and LMIA by applying to employers directly (rather than using a consultant). Too many consultants are scams.
