Travel to Costa Rica to Build a House

I am part of the American Field Service (AFS) club at Erskine Academy. Last year the club went to Guatemala to build a house for a family in need. This March we will be taking another trip to Costa Rica to build two more houses. The money I make will be used to pay for my trip to Costa Rica so I can help build the house. I need to raise at least $800 in three weeks for the initial payment for my trip. I need to raise the other $700 by the end of December 2019. I would greatly appreciate any donations to help me pay for my trip. It would be an amazing experience and I would really like to be part of it.
