Search for local volunteers to join a non-profit organization or activity by using sites such as HandsOnNetwork.org, VolunteerMatch.org, Idealist.org or AllForGood.org to post requests for volunteers and contact interested parties, as of 2015. Alternately, post on the Volunteer section of your community's Craiglist.org page.
The Hands On Network offers nonprofits access to its database of volunteer workers and training information to any entity that signs up for a membership with the organization. It also provides members with online training resources and consulting services to help organize and implement events. VolunteerMatch.org allows nonprofits to post ads for volunteers or to search through volunteer profiles in order to locate any local community members looking to engage in philanthropic activities. Idealist.org operates in a similar fashion, where volunteers and organizations are each able to create accounts to view available postings about volunteer opportunities.
AllForGood.org offers both a free account option for organizations searching for local volunteers and a premium membership service that provides recruiting services. These services consist of members of the site's team helping the organization connect with volunteer sourcing entities to staff different events and projects. Craigslist.org enables any entity to make a free ad requesting volunteers for an event or charity. It doesn't place restrictions on the event or the listing.
