Make a really clear plan, show them how many hours it took to build it and explain what kind of support you could offer. If a web presence is important to them, the charity should be able to budget in support hours after delivery. I usually volunteer a fixed number of hours after delivery, limited to a period of time. It helps them understand what your time is worth and that communicating ahead of time is what solves all (most) issues. If you're not able to commit to support, use WordPress or another very common framework so someone else can pick it up and don't skimp on the comments/documentation.
