What are some good ways to sponsor a high school prom? Ask the venue to cut the students a price break, host a bake sale, car wash, dog wash, sell candy, or see if local businesses will donate in exchange for some free advertising at your prom, get on www.gofundme.com and write a compelling story, post a you tube video, host a giant yard/rummage sale. The above suggestions are a few of the things we do in the states. I hope those ideas help! Best wishes!
