This is a good project for well-supervised volunteers. After you create a budget for your newsletter, determine your financial resources. You might simply designate a portion of your organization's membership contributions for the newsletter. Perhaps you have a patron among your members who will either provide e seed money, or long-term financing. Many newsletters are subsidized out of the pockets of the individuals who produce them.
Some groups offset expenses by selling subscriptions, or advertising space.
The Internet now makes it possible to publish your newsletter electronically through your own web site. In fact, some newsletters are not printed at all, but available only on the Internet. Publishing a newsletter is well-worth considering. While hard work, it can be exciting and rewarding. If your group has something worth saying, you should definitely consider publishing a newsletter.
