I've worked with Take 5 Labs (http://takefivelabs.com/ http://takefivelabs.com/) for iPhone app development. They developed an app for the last company I worked for (http://www.veritasprep.com/iphone-gmat-practice-quiz/ http://www.veritasprep.com/iphone-gmat-practice-quiz/). That app was in the $5-10k range.
