Many businesses and organizations are looking for ways to support youth in their local communities. Approach businesses and organization and ask them if they would be willing to sponsor you. It is helpful to provide them with a professional letter (like the one here). This letter should explain what organization you are volunteering with and what the cause is. Offer to do a presentation for them when you come home about your Build and how much their donation supported you and the cause. Some organizations that may be willing to donate are your local Rotary club, Kiwanis club, or major franchises that would be proud of the fact that they sponsored a youth in their community!
