support village evangelism

We are a School Fellowship that goes for Village Evangelism at the end of each session,and  also for other events like conventions to aid members spiritual growth... a lot of money is always spent on transportation,leaving just a little left for feeding,bibles and books and other gifts for the villagers...we are a school fellowship and we need to cut cost on transportation,so we thought it will be better to own our own coaster bus instead of always going out to rent. Every amount donated will be very much appreciated
