Bug fixes on existing iPad App + enhancements

iOS programmer wanted to fix and improve an App that is currently on sale in the Apple App Store. The app was developed for iOS6, it works in iOS7, just some existing bugs and a few changes to be made. The app is a specialized tool for tracking continuity on film sets. The biggest trouble is in the Continuity Page Print-outs Bugs include continuity photos printing in duplicate, Photos getting cut in half when printed, and there are some issues with the auto sizing of the photo print outs. There are also one or two actions causing the app to crash. I can discuss those in greater detail with interested candidates. Continuity Pages can also be emailed from the app, the email function has been known to stop working from time to time. Upgrades and Improvements I would like to make include adding some new features. I would like to implement a sharing feature. Keeping in mind the app is already in use and users will have their databases stored on their iPad, this new feature will have to happen seamlessly so the Apps that are being used already do not lose their data. Going back to the topic of photos, I would also like to add an option to import multiple photos from the iPhoto library (currently you can only import one at a time)
