Raleigh international volunteering in Costa Rica

Hi, my name is Finn and I am raising money to help fund my trip to volunteer in Costa Rica with Raleigh International in summer 2024. Whilst in Costa Rica I will be completing 10 weeks of conservation and building work (building a school). I have a paid weekend job which is helping me to fund the trip but it won't be enough on its own. I'm looking to raise £1000 to help pay for the rest of the expedition so am willing to work for £10 hourly doing odd jobs, gardening, Etc... Any additional donations would also be greatly appreciated.

Thank you!
