Finalise my nearly finished app

Hi, I have an app that is coded in iOS and Android. It is a fairly simple camera app that allows a user to add details to a photo and export the photo in various formats. It is functional however I need it to be glossed up graphically because it was originally coded a couple of years ago. I also need a few bugs ironed out and some small changes. Finally, I will need assistance getting the app on to app store and play store. If you have skills in iOS and Android development and you feel you can help me out, please let me know. I envisage the project will take about 30 hours of work in total and I would be interested in a long term relationship with a good programmer that can develop some new ideas that I have, from the ground up. This would be conditional upon successful implementation of this project.
