As a freelance grant writer, your responsibilities are to provide a range of research, writing, and editing services to a client who needs help with preparing a funding proposal. Many nonprofits and other types of non-governmental organization, such as academic research facilities or universities, rely heavily on securing grants from private foundations and the federal government, which is a major research funder. Your duties include researching potential funding sources, working with researchers or project managers to determine the necessary budget for a project, and writing a proposal that includes the aim of the study and its timeframe.
