Enhancements to an iPhone/iPad app

Are you a strong independent developer? Are you reliable, professional, responsive and you love challenges? If you answered yes to all these questions, I would love you to be my new developer. Over the past 3 years I spent $2000-$3000 each year on my apps. My old developer is now too busy and I need someone new for future development. This project is going to be small and you'll need to spend some time understanding my code, but if you do a good job you'll be my first choice for all future projects. I think that it's worth your investment. So... this project is related to my newest app: [login to view URL] The concept of this app is simple - the user selects a photo and then each page has color flashcards hiding that photo in different costumes. This app needs some minor enhancements to make it really good: 1. The code currently randomizes between a few costume images in each page. I want to change it to simple rotate through the images instead. 2. After a few pages, if IAP is not bought, the app stops showing the user's photo and instead shows a default photo. Unfortunately many users don't understand why. I need a pop-up message added to that page, explaining this behavior and linking to the IAP. 3. There are also a few small bugs that I need fixed: a. When selecting the face in a photo, zoom in works but zoom out doesn't. b. When randomizing between images, the sound files associated with these images don't play c. When selecting a new photo, the page doesn't refresh correctly and displays both the old and the new image d. IAP button reaction is too slow so sometimes people tap it twice. Need to add immediate feedback to this button. That's it. I think that this is only a few hours work for someone familiar with the code. You'd obviously need to spend a few more hours learning the code. My budget for this is $300 or best offer. If you have additional ideas on how to improve the app, you will definitely get bonus points with me. Again, this is a long term opportunity rather than just one project. Thanks, Shira
