Boxing has always had better attendance that's why Kickboxing shows now put boxing on to help with ticket sales.

Kickboxing has always been a local thing with local guys fighting each other for free, local title fights v foreign opponents as long as the fighter does ticket sales to cover opponents costs, or fights for deducted purse or sometimes even no purse just to get title shot.

Then when you want to defend no one wants to pay defence purses and just fights for another or vacant title.

Not digging mate Ive put massive shows on myself under WAKO ISKA WKA etc just saying if you want to start a new concept and want the top fighters unfortunatally you have to pay for it.
I'd personally go big (with an 8 man and rest of the show with local b-c class fighters to keep costs down but still have 12 bouts)to set the benchmark and get more top guys and girls interested for next one.

Fighters will always sell tickets from there area, but promoter should always be pushing the show.

Fighters should concentrate on fighting not being a tout. lol

Maybe you should do some b-c class shows 1st to keep costs down then when you have more in the pot you can go bigger.

You do need that rule set 1st before asking fighters to fight cause 1st thing they will ask is what are the rules, whats purse or winning pot for 8 man and what equipment do you wear :)
