If the IFBB wants bigger shows, they have to cut the sanctioning fee's out for 2 years. There is no way someone is going to do a pro show these days, in a decent venue, advertise it properly and make money. If you run a full event, meaning women/mens bb'ing, fitness and figure it will cost you 75k with the prize purse and sanctioning fee's. Include the rental of your venue, advertising, staging, lighting, labor, union fee's and hoards of other shit, there is NO WAY it's going to make money.
People don't go to bodybuilding shows, get that through your heads. That is why I did the FIRST ever webcast of a bb'ing event. For shows to make money they will need to offer a service like this in a PPV type of format. The events simply won't draw enough people otherwise.
