This is not true. A good person for your group is someone who first and foremost believes in your group and wants to be part of it. This person will express his or her belief through fundraising, just as someone else is expressing their belief by doing direct service, organizing, or policy development. If someone who meets the criteria of believing strongly in your work has fundraising skills but can't afford to work at the salary level you are offering, you may need to reevaluate everyone's salary. Once you have decided that you need a development director, you need to create a fair and accurate job description and begin the hiring process.
Many job descriptions fail to attract candidates because they contain too many responsibilities.
Avoid the temptation to add components to the job that are not related to fundraising or public relations. Think about what skills are essential as opposed to those that are desirable but not imperative. When interviewing, ask for writing samples, since writing will be a large part of almost any fundraiser's job. Advertise in publications geared to nonprofits. Unless you are in a small town, avoid advertising in the newspaper.
