I'm used to work with iOS (Objective-C) and SQLite, and I am able to develop what you need with extremely perfectionism.
Here, at freelancer.com, I've worked with Kyle Begeman on a Huge iOS app. I've written massive code for both server and app side, and it includes and SQL database. If you want, you can contact he for tanking recommendations of me. I can guarantee you that he became extremely satisfied with my job.
Thank you in advance,
Igor Silva.
