It is important to establish a clear and accurate budget early on, as soon as you start thinking about facilitating a bottle school project. Always look for ways that you can get materials donated or at steeply discounted prices.
Municipalities, cement and iron companies, local suppliers of sand and gravel, local hardware stores, and other organizations are all places you can reach out to first. Aside from the importance of keeping the community involved and clear on each step of the project, having a respected community member work with you as you seek price quotes and discuss materials with hardware shops can allow you to utilize close relationships within the community. Such relationships can result in smooth transactions, discounted prices, or donated materials.
