Porting Unity game for Android to iOS

I have an Android game (already released on Google Play) that I need ported to iOS. I don't have a mac or an iphone so I figure this might be the cheapest way to do it. The game is already fully functional and for the most part uses very few external library and only internal C# classes. The libraries that might need additional attention: - Unity IAP so that it will work with the iOS store. - Google Play Game Services for leaderboards and achievements. Would be nice to get the Apple Game Center implemented as well but we can talk about this. - Everyplay recording (but this might just work fine as is? Doesn't seem to be a lot of extra tweaking) - Unity ADs (but should be fairly straight forward?) Also want the developer to do testing on iOS devices and take screenshots for both iPhone and iPad. I expect a release-ready version to be returned along with the new code and explanations (in-code comments are fine) for what's different. I will of course supply keys and certs from apple store as well as linking code to the Google Play Store. Since it's a fairly simple porting project it shouldn't take more than a couple of days.
