iPad Calculator - iOS Dev need with existing code. - repost

I need a simple calculator with custom changeable background created for the iPad. I'll need the following: 1. A developer who already has the Calculator code, we don't want to start from scratch to keep the cost down. 2. We will provide an Image that will be used for the background of the calculator. You'll need to work with us to get the 'rigtht' look, there might be some tweaking and back and forth changes till we get it right. 3. The background image will be scrollable left to right so the user can pick a new background image. I will provide upto 5 images. 4. Flurry analytics integration 5. iTunes Connect submission. 6. Source code PM me examples or links to screenshots of your existing calculator. The budget is under $200 - we really won't even review anyone over $200 for the project. You should have existing code to complete the project.
