I suggest you investigate community foundations in your area to see if their missions align with your goals. They have preferred tax status, enable you to leverage the impact of your donation by pooling it with other like minded folks, and sometimes have arrangements where they self-fund the administrative costs, which leaves all of your donated $ going directly to recipients.
