Your biggest problem is probably that Objective C developers are in extremely high demand. They can make a lot of money, or if they have an interest in start-ups the barrier for entry is so low to get in the app store that they probably don't see a need to partner. Everyone has a dozen ideas for cool apps.
It sounds like you have a pretty compelling pitch, but you are pitching to a very small market with tons of competition.
Yeah, that's kind of the conclusion I came to. But that just makes me ask the question: Then why doesn't every developer with a related skillset just learn Objective C already and try to charge me lots of money? I mean, if I didn't already have two jobs on top of spending months of the year on tour, that's what I would do. Sometimes capitalism doesn't work.

Good luck!
