I have been developing for iOS devices since the SDK was first released. The first app I developed was the highly successful iBeer. If you wish to view a more sophisticated app that I developed take a look at ARSSN, which is an augmented reality art creation program, that allows users to save their creations by GPS locations, allowing artwork to be searched on an interactive map. I'm currently developing a project for iWatch, although NDA restricts me from telling you about it, but I can tell you that it's basically complete, and just waiting for WatchKit to add the last bits. I'm extremely excited for the possibilities that this device offers! I know my budget is a bit higher than your request, but I tend to work very fast, so it should work out well for your purposes. I look forward to hearing more about your project!
Thanks,
