Low-Cost Inpatient Rehab in Houston Area?

Good evening,

I've just learned of a family member's methamphetamine addiction, and in the unlikely event that I can get him to admit it and agree to treatment, I'm going to need help finding a low-cost inpatient rehab treatment center in Houston. He's not on my insurance, he doesn't have insurance, and he's done things in his life that have left him without access to medicare or medicaid. The family who is left who will talk to him have a pretty limited budget as to what we can do to help, and some of us are aware that making this investment could be for naught, and want to be cautious about how much we sink into it.

If anyone has experience with this kind of thing, and feels like sharing either in a comment, or preferably a PM or chat message, I'd welcome your wisdom and experience. Thanks for your time, Houston.
