Uganda

Now in this day and age, people are looking for that extra something, a thrill, lending a hand, looking after someone who needs any support they can get.  My school do this thing called the Uganda Expedition, where a group of sixth formers, go to Uganda, help charities, Orphanages and schools, build, create, and store water, house people, and teach children.  In all honesty, I am one of those people going, but I have to raise £2,500 pounds in order to get there by next summer, I am scared, so far raising money is difficult, I mean what do you say to companies whilst in an Economic downfall.  I want to ask, but I feel like I am going to be rude, So what do you guys think, what should I do?
