As someone said earlier, we need an assessment of materials needed so we can go on the blag. I would then be able to keep an eye on my local Freecycle group to see if anyone was disposing of anything needed, plus I could put a wanted ad on there as well. If it gets official I could approach my boss/company to see if there was any remote chance of squeezing some cash from the charity budget. I'm concious of not letting the momentum die on this as I'd really like to help.
May be worth considering the aftercare i.e. see if there is routine maintenance we could help with?
