1. Have a bake sale and sell cookies. You can easily sell 100 cookies in your neighborhood.
2. Organize a game (ring tossing or arrow down balloons) for your friends and charge some fee. May be $5 pp.
3. Sell lemonade. Just one weekend work?
4. Request sponsorship for games or gifts from friends. Conduct auction of these gifts.
5. Check this link for more ideas  
6. Some companies have Gift matching program . So some of your donations can be doubled and it will be very easy to reach your target. If you can get 2 people with gift matching program to donate $50 each, you would have reached your goal as that $100 will be doubled.

We will be adding more to this list as we go. If you have any ideas, please email us at events@janyaa.org
