Location based search on what help is available can be done on the app and web.(www.webcrs.com/reachout2help). Direct numbers of the contributors are available on the app and link. The needy can also submit their requirements which are stored and shared to those who are willing to help.
People who can offer help can update and manage their capacities to support others like number of further people they can accommodate in their house/facility. This will avoid unwanted calls once the capacity to accommodate is full.
