Teacher volunteer in Bali

My name is Sevanna and i'm 19 years old going to Bali (Tabanan) to volunteer as an English teacher for 6 weeks, i have also extended my stay to enjoy Bali. During this time I will not be receiving an income as its voluntary work. I have saved enough money to support me whilst living in Bali. I would like to raise money to cover some of the expenses towards my trip but I would like to use most of the raised funds to go towards buying school items and everyday life necessities for the children I will be teaching. Any donation will be greatly appreciated!
