The Gambia is on the west coast of Africa and totally surrounded by Senegal.
We used The Gambia Experience for booking flights and they helped us find cost effective ways to get ourselves and the donations to The Gambia.
When we stay in Banjul we use Luigi's. Luigi is Italian and Julie is British. They started Luigi's as a Pizza house in 1995 and developed from there. They massively support the Jofi Preparatory School and accept donations and student sponsorships for the school.
We rented a mini-bus and driver from GamBLE (Gambia Building Link in Education). They are a UK charity supporting projects in the Gambia. The mini-bus and driver is one of the ways they fund raise.
