First, search for oral history projects in your area. These are often funded and need people to listen to the stories of the old. You can also try to connect with elder care facilities. Sometimes they collaborate with researchers or media to share the stories of their residents. If you can prove your skills in interviewing and documenting, you may get paid for listening to old men tell their tales. Additionally, look for freelance opportunities on job boards where there might be requests for people to collect stories from the elderly.
One way is to look for work with local historical archives. They often seek people to interview old residents, including old men, to document local history. Another option is to contact non - profit organizations focused on cultural heritage. They may have projects that require listening to the stories of the elderly and are willing to pay for it.
