Funding for volunteering in South Africa

I am doing a sponsored 36 mile walk from Spurn Point to Wyke College because I am going to South Africa in Feb 2016 to volunteer for 2 weeks, working for a charity called Botshabelo (www.botshabelo.co.za). Botshabelo is a multifaceted charity based is Midrand, South Africa. They are passionate about transforming children's lives through excellent education and providing the best possible start for children. I will be working in the babies home, the preschool education centre and taking them on a school trip, something they wouldn’t be able to do without us there to help. I will also be building new dwellings for local families that are in desperate need of a new home. Thank you for any donation! Emily!
