Hello,
You need to add description to your images? I've recently made a test application that does just that. It add text on image and saves it. If you can describe me what exactly you are looking for, I'll be able to help you with this. I'm new to this website and this might be my first job but with my 3 years of experience with Android, I know I can help you with this.
I'll keep the starting price bare minimum. Try to give me a shot, and you will find that I'm worth it.
