When you come up with unique fundraising ideas you need to think about a few things. You need to know what your resources are, skills of people who can help, and what will attract a crowd.
Knowing your resources can help you in coming up with unique fundraising ideas. These sorts of factors include facilities at your disposal for hosting an event, things which you have to sell and others. If you have no resources to begin with, this does not mean that you cannot hold a fundraising event, just that you are failing to take advantage of something which you have not thought of. A lot of fundraisers can be done on little to no budget.
You should also consider the skills of the people who are willing to donate their time for the fundraising event. It the fundraiser affects them at all then they should be willing to donate their time. If people in your group have skills like baking really well then you might consider a bake sale. If you have an art teacher in your group then maybe you can hold an arts and crafts event. This often works well when parents bring their children in to creatively make artwork and sell it to the public. When you know your group well then you can come up with some really good ideas for holding a fundraiser.
Another thing you need to think about when you are holding a fund raising event is that you need to know your community. When you know your community then you know what they are likely to respond to. You should also be sure that the cause you are trying to raise money for is something people will care about. This means that you need to know people believe in the cause.
The part of town in which you hold your event also matters - a fundraiser in the poorest part of town will probably not raise nearly as much money as one held in an affluent neighborhood.
Think about which local businesses and organizations are likely to support your fundraising mission. For instance, if you were to raise money for a book club or library, perhaps local bookshops would be willing to assist your cause by donating books to be sold at a fundraiser. No matter what your fundraiser, look for organizations that have concerns which are relevant to your own.
Grocery stores also have book sections and they may be willing to let you put out a table for a bake sale. There are public places and businesses that will be willing to allow you to hold your event on their premises.
To come up with unique fundraising ideas, think about all of these things. Knowing the skills of your group, the resources available and the nature of your community will help you to come up with an event which will work well for your group.
