And how would you answer the question?

Can you tell me how I can guarantee my revenue share from paid and free versions?

If it was him that put my game in his account, I would put a remote kill in the game for the paid version if he didn't pay, and the ad supported version, I can make the game toggle between his admob account and mine when serving ads.

But if control is solely mine as he suggests, what assurance would I give? To be honest, I hate the marketing part and I just want to code so if this was real, it would be excellent.
