Donating from photo shoots?

I was thinking yesterday about how many people there are that are in need of something and I really want to take part and help out because I really hate to see people suffering or needing (not wanting, necessarily) something and being in a position where they are unable to meet a need. So, I was thinking that I would find an organization, a family, an individual...whatever, to donate x-amount of my earnings from photography/art that are scheduled during a month's timeframe. I just need to find a cause that pulls at my heart to do this for. Any thoughts or suggestions on where to donate?
