Volunteering in Fiji

I am planning a volunteering trip to Fiji, which will consist of me caring for vulnerable children, helping to provide them with an education they otherwise would not have access to, to open up future opportunities and help them to learn English, a hugely valuable skill for these children to have.
Many of these children in Fiji are extremely poor, with struggling families, and many can end up living on the streets and engaging in damaging activities and behaviours in their future. Volunteering programmes are one of the best ways to support these children to have a safe, secure future, access to an education, and childcare where required.
As a volunteer, I will be going to Fiji for one week to begin with, as my first volunteering trip abroad, and will be planning creative and engaging ways to deliver lessons to children ages 4-5 in a kindergarten setting. I will also be helping with the teaching and childcare programmes as a whole, delivering lessons and caring for younger children in the mornings, and assisting with the programme as a whole during the afternoons and evenings.
The volunteering is planned for September currently, though is subject to change. I am hoping to raise my minimum needed amount to help me fund the trip, any extra donations if the target is reached will be hugely appreciated, and any surplus will be used by me to purchase items needed for the trip, such as notebooks, musical instruments, stationery and any other lesson materials.
Thank you so much to anyone donating or considering donating, it is hugely appreciated!
