We’re in Caldwell, New Jersey and Need to Find Low-Cost Drug Rehab Programs. How?

We’re really strapped for cash. My husband got fired from his job because they discovered that he’s using heroin. My income alone will not be enough to get him into a drug rehab. One of my three sons is already working, but he’s already got his own family to feed so I really can’t ask for too much. We have no relatives nearby and I don’t know anyone whom I could turn to for financial assistance. Can anybody give me ideas on how I can put my husband through drug rehab? And please don’t say I need to get a part-time job, because I’m already doing that every spare time I’ve got.
