Who can you ask to sponsor you to help you with obtaining your cfr medical kit?

You need to ask whomever's organizing the program and acting as chief operating officer. Even though it's apparently a community project, there are still standards that are delineated and must be met, and one of these is the composition of your kit. Because you're a community organization (I assume), you can become a tax write-off (maybe) for contributors. I've seen this work well where a major drugstore chain took on the burden of supplying the kits. You'll see the same type of thing with volunteer firefighters and such. The answer then -- to me anyway -- is, whomever is running this needs to take on the task of logistics and supply. Unless that's you, this isn't something you should try alone, as I imagine you're not an official representitative of the volunteer organization and cannot commit funds or issue receipts in its name.
