Enlistment?

How long does it take for military enilistement? How long does it take between enlisting and getting financial assistance? My husband and I will probably be evicted in 2 weeks. We have our 11 mo and we have no friends or family to help us out. We live in LA and can't afford our rent $2000. We both applied for personal loans to pay for rent for May/June to buy us time. But we both got denied. We have been on the childcare assistance waitin list for 5 months and filled out the application for housing assistance and will be on the waiting list. We have $200 in our account and waiting for next weeks paycheck. Our only option now is for hubby to join the military or go to a homeless shelter.
