Its £2500 just for the fee to the council to re-submit the planning application and around £1000 for the consultancy fees.
I don't think it would be right to ask for donations for something that might not come off.
What would be more useful if it does come off is peoples skills - ie ive got a huge industrial heater that will run on waste oil, so we could heat the building for free but need a plumber to install it all
