Below are a few unregistered domain names I believe have good potential. Although I am not charging anything for researching these names, I am requesting that the person who registers each makes a donation to a non-profit charity.

AngerManagementCounselors.com
AngerManagementCounselor.com
AlcoholTreatmentClinic.com
AlcoholTreatmentClinics.com
NarcoticsTreatment.com
NarcoticsRehabilitation.com

A few charities I recommend (with the link to make a donation):

Dana Farber Cancer Institute
ALS Association
Simon Wiesenthal Center
The Doe Fund
Meir Panim

**EDIT**
I received word from the person who registered the 6 domain names that a donation was made to http://www.kiva.org to help with this project:
