Publisher stuff

[SIXThBIT]

Hi there, I am planing to submit my almost finished iphone game to few publishers for review. How do I submit an iphone game demo(or fully finished game) to publishers? I mean with all these itunes connect stuff(provisions,distribution certificates etc), And if my game got selected, then how do we work around sales reports,updates(again with itunes connect) etc?

experienced developers...please help..thanks a lot
