I'd say the first step is not re-inventing the wheel. Identify and leverage existing resources.
Second, start with needs in your own congregation.
Third, go back to step one, and identify where there are holes in the existing resources that you (corporately or individually) might fill or what existing programs you might feel called to help out.
Fourth, guard against opening your wallet to the scam artist with the best sob story. Coordinate with the folks you identified in step one to avoid double dipping, and search out those too modest or ashamed to ask for needed help.
