Funding for theatre project

Hello all,

I'm an actor and writer. I have a play, a cast and a possible venue. What I don't have is the cash or the knowhow to raise it.
Before you click away I'm not asking for people to put hands in pockets but any ideas would be appreciated. Perhaps you work for a philanthropic company or have a ridiculously wealthy Great Aunt and so forth.
The Arts Council are a long shot as money is so tight in London so any other options are currently what I'm looking for.

Any ideas?

Jimbo
