Working in the events industry?

I've been to the Birmingham NEC lots of times to see different shows and always love the vibrant atmosphere - lots of people, fun, energy and things going on. How could I possibly get into this type of work? Admittedly I've no experience in this sector as I currently work in manufacturing which I find really boring, no fun and far too predictable. This is why I want to make a major transition in my life into something completely different and completely unrelated to manufacturing, warehousing or factory work. I'm more than willing to do voluntary work to get a feel for jobs and gain invaluable experience if I can clinch myself something. I will also say I'm not 100% knowledgeable about what is available in the events industry, so apologies for if this sounds a bit vague or untargeted. I just want to work at big events in some way, being amid all the vibrancy and energy. How can I do this (or make inroads into it) from the point of a complete novice without experience? Also from my description, what types of entry-level positions do you think I could look at - not security roles or litter pickers, actually in events meeting visitors, having fun and being a part of what's going on? I suppose something like when I went to the BPM DJ Show at the NEC a few months ago and there were girls at the pioneer stand walking around handing out leaflets and taking photos for the Pioneer site. That kinda thing, in events taking part. Thanks for any info you can give me.
