Essex "dry hire" venues

Hi, not sure where to start or if there are "busier" websites and forums to look at...! But, I'm looking for budget friendly venues in Essex where we can supply out own caterers and supply some of our own drink (would also like a bar to be available too though!)


Any ideas of where to begin!? A lot of venues seem to have package deals which, we are not really interested in as we want something fairly small and informal
