Often, the number of people you work with will be determined by your goals -- larger goals bring with them the need for a larger team. With the right volunteers on board, responsibilities can be shared, fostering cooperation (and an easier life for you) and a greater sense of "this whole thing being ours" within your congregation.
Who's the Boss?
Are you going to be in charge of your fundraiser? If not, who is? We recommend a team leader who's enthusiastic about the drive, the cause, and what you'll be selling. Someone who can motivate and draw in other members of your congregation is indispensable for a successful project.
Dealing with Money
Be sure that you've got a least two people on your team who are comfortable and reliable with money matters. One of these should be your fundraising leader, while the other can serve as treasurer for your project. Both should be present when counting any moneys collected, and both should sign all requests for money using a numbered receipt book for all cash disbursements. Accurate records of all money collected are necessary for a well-run fundraiser.
Deposit money collected promptly - preferably daily. In between bank deposits, make arrangements to keep collected moneys under lock and key.
Before Your First Meeting
Get advice from people who have run fundraisers in the past. What has worked for them? What hasn't? What advice do they have to give you? Talk with various members of your congregation to see what people are interested in selling or what they're excited about volunteering for.
Find a few people whose opinions you value and approach them about getting involved with helping to plan your fundraising drive. If they're interested, try to provide them with fundraising resources (like books or websites such as this one) to read before a potential meeting, so that they'll have a good idea of what the options are and be able to make useful and informed suggestions.
Find a time when all of you can talk together for a few minutes, whether it's Sunday after your morning service or a weeknight when everyone can get together.
Choosing people from different parts of your congregation will be helpful, as well - some younger, some older, some men, some women. Making sure that everyone has a voice will make for greater participation and a good spirit of community for your drive. Your first meeting can be an informal brainstorming activity, with lots of different ideas being discussed. Small baked goods and coffee can be great facilitators for comfortable conversation.
Putting together a team will help to spread the responsibility and the sense of ownership of the drive throughout your entire religious group, helping to foster a sense of community.
