Only option I see is sending through the mail to them - massive risk though as you never know if you will get it back when you send TTM.
If you do the research quite a few are not hard to find.
I can start you off - Geoff Lawson is the bowling coach for NSW so he would be easily obtainable through Cricket NSW. He is a really nice bloke, he may even be able to assist with some of the others on there.
Andrew Jones is NSW Cricket CEO. assume is same guy as on poster. Gavin Robertson does radio on 2SM in Sydney, Mark Taylor works for channel nine, Mark Waugh channel ten and cricket Australia.
