I dont know the cost involved in other states but here the $700 - $800 for the compulsory training sessions, practice sessions, Rachuig trials, State Championships, State Masters & a couple of compulsory tournaments. The $1,200 - $1,400 for airfares, accomodation, national events, uniforms, diner tickets, linage costs etc. The $700- $800 for a couple new balls if you need new equipment & the $1,000 in lost wages while your away if your employed on a casual basis. $3,500 - $4,000 bucks is a lot of money for a 9 day trip.
Unfortunately, some of the most talented bowlers are not always the most financial & cannot afford the costs invovled. The 80's & early 90's where great when you made the State Team & all the expenses where covered & you even got a bit of spending money from the State Association.
I think if your looking at Sponsorship, you should be approaching the Bowling Centres. All these centres put there game rates every year. Get every centre to throw there game rate up an extra 5 cents a game. Even if you only got back a 2 cent kickback per game for every game bowled in each centre for the year out of the 5 cents and the centre kept the rest your talking enough money to split between all states to cover most of the costs for your Rachuig, De Veer, Shield & Seniors teams every year.
You'll probably get the centres complaining why should they be putting money into sending these teams. There not, It's a user pays scheme, it's the people using there facility that are sending these teams away and the centres are making a few extra dollars on the side
