Does anyone know of any longer term Christian post rehab programs?

My son has been in drug rehab for 38 days and we are looking for a chrisitian program where he can go to continue working his sobriety that doesn't cost an arm and a leg. Does anyone have any suggestions?

Salvation Army has a recovery program. Also the patient can work for the cost of treatment at the rehab, so it's what you are looking for I think. I know there is one in Seattle, not sure where else. Maybe look up Salvation Army in your area and ask.
Salvation Army is christian based, but they don't turn away nonchristians.
