Extra Breast Pump

Hey all, Just trying to see if anyone near southside has an extra pump or one no longer being used. I have no formula and have been feeding my son by pumping with my pump but it broke. I can’t tell how much he is getting and he always wakes up after an hour to 15 minutes after feeds like he never ate. I don’t have money for formula or another pump so just trying to see what options I can weigh. Thanks in advance!
