There are numerous firms that specialise in Event Management. Besides these, most advertising and PR agencies too have separate Event Management arms.
Many dotcoms too have their own Event Management arms, specifically tailored to suit their needs. If you manage to make good contacts, you can even work on your own or freelance for major agencies.
Miss world, Miss universe, Miss Asia pacific, Miss India, Miss Chinchpolkli… Isn't it obvious? There are way too many events being held these days it's increasingly becoming difficult to distinguish one from the other.
If you come up with something out of the way and interesting then you could blow your bugle. Conversely if your show flops, then be ready for instant brickbats. You could even diversify into set designing, lighting or music coordination.
