The exact cost of the project will become clear after the meeting and a detailed discussion of the project: in the process, many issues will arise that will affect the final amount (we can talk about photographing relatives in another city, printing an offline version of a book on paper of one quality or another, or digitizing VHS tapes — each the project is individual).
On average, a project involving several family members will take about a month to complete. An interview with one relative can be done faster (within 10 days), and if two dozen people tell family stories, the total work time will be from one to three months.
