Hi Elihu5991,
My name is David Brooks and I am a current Junior at Loyola University Maryland in Baltimore, MD, USA. I am earning my BS in Computer Science and have been doing iPhone Development for the past 3 years. Unfortunately, I will not be able to do this project in Android for you, but I am very confident in iPhone Development. I have already worked on a project that implements photo storage using Core Data that can also store categories and tags. The conversion of an image to a pdf that is then emailed is fairly easy. I also have my own In App Purchase Manager that makes its implementation very easy and only takes up 12 kB. Please look at my portfolio to see this manager as it is found on my Github.
Please let me know if you have any questions! I look forward to discussing this project with you further!
Key word: Photo :)
I have fully read your requirements and feel confident in successfully completing this project for you.
Thanks,
David Brooks
