Enfield Green Party's General Election

We are a small party, and a second general Election in 2 years is too much for our finances. We cover 3 Parliamentary constituencies (Enfield North, Enfield Southgate and Edmonton). For each we need £500 for the deposit and (ideally) £700 to pay for a Freepost leaflet to be delivered by Royal Mail to every door in the constituency (the delivery is free, but we have to pay for the printing). We have some money but not enough - can you help please? It's so important to get the messages across that climate change needs tacing urgently, and that the Tories' vicious austerity policies are crippling the country.
