Apply changes to Android app - More work to come

Hi all, I'm looking for a good and experienced Android programmer to apply small changes/fixes to a current project I have been working for a couple of years. I want someone that I can delegate the task so I can keep working on other projects. The developer should be cost effective, professional work and good timing. If he or she is able to work on the project with success keeping an appropriate cost to delegate task I will come with more ongoing work for different projects too as they come to me. I need to make a trustable relationship so he or she can help me with different projects. In this case it is a quite large application which is already on the Android market with a very good positioning. In general lines here is what I need: - Apply Holo theme to all the application making sure everything keeps working. - Apply high resolution images for bigger devices (I will provide the images) - Swap tabs on a tab pager - Check required permissions and remove those not needed - Few more small changes For this project I don't expect a cost higher than 250 USD otherwise I cannot assign the project. This will also help to test the developer for future projects or enhancements to this project. I will provide further details to possible developers on this project. To the selected coder I will provide full source code to work with. Estimated time should be about a week and I'm restrict with the timeframe. Please all your Bids start with 'dragonfly' on the private message otherwise I will ignore the messages as that means you were not reading the whole description. Thanks, any question is welcome
