Hire Space - www.hirespace.com

I have been trying for a couple of weeks to find a wedding venue that allowed me to bring my own caterer (we found that approved caterers were a rip off)I eventually cam across this site which has a ton of cool spaces that work. I'm going with Pimlico Academy!

I mainly just used the search and enquire function on the site, but did have a call from a women from the website, who was very helpful and sent across some additional options.
