Breast pumps are not cheap but maybe you can borrow one (I think Obama care gives you one for free if you're poor)? I'm no expert though (being a guy) just have recent (just short of a year ago) experience helping my wife through SO MANY breastfeeding issues (terrible mastitis, latching issues, you name it we probably had to work though it).
EDIT: Just saw you've had multiple kids, you know more than I or my wife about the breastfeeding/pumping
