Try writing grants as well as business sponsorships-- Lowe's grants are made for this purpose and hit up some of your larger businesses in your area-- maybe they would sponsor some of the equipment and in exchange you place a plaque on the equipment and advertise all their support in your efforts.
When our new school was built in 1992 we did not have a playground and it took us 3 years to raise enough money to buy play equipment. To raise money you could do a "I support (Your school Name)"ad booklet. I did this to support our volunteer fire department several years ago. Sold ads to business and community members...I sold the ads at different prices, I also had a page you could have your name put on for $5. and I also printed these at our church at that time..you can make a lot of money at a low cost to your self. Hope this helps you
Trying to raise money to replace and update our playground equipment. Does anyone have a business proposal that they used or have any suggestions I can look at online to submit to the District?
