SE1 Nightclub Hire

Hi all. I'm looking to organise some club nights in London. I did this when I lived in Prague and they were really successful. I want to do the same here but I'm having trouble finding suitable clubs that I can hire. Been trawling google for weeks now.

Does anyone have any recommendations for small-ish clubs in SE1 that can be hired for a Friday or a Saturday night and would allow various genres of electronic music such as house, techno and trance to be played?

Thanks for your help.
