Community service trip to Costa Rica

Next summer, my son, aged 16, has chosen to give a month of his time to go on a community service trip to Costa Rica. Whilst there, he will be participating in local community projects. These might include building work or other manual labour jobs, he will find out closer to the time. In the meantime, he is busy fundraising to cover his costs so that there is no negative financial impact on the charity or community. We would be so grateful for your support.
