I'm pretty intimately familiar with the whole industry. I once owned a small (~2k person) club / live music / multiuse venue in San Francisco as well as built a ticketing SaSS for USCF (us cycling federation) sanctioned events.
From the club days, I got subtly screwed by Clear Channel on an event once and it really left a bad taste in my mouth. From the cycling ticket stuff, I got to deal with another type of promoter and that was horrible in a lot of ways too. Both businesses eventually failed from external factors.
I don't envy your sales team at all.
