I am a professional Actionscript 2.0/3.0 developer with years of experience both in the freelance world and the big companies in the industry (Electronic Arts/Gameloft), having worked on FIFA 14 HD, Total Conquest and The Dark Knight Rises.
The photo booth project that you want is actually pretty straightforward, I can do it with ease, especially given that you already have the graphics.
I would be happy to work with you. the link to my portfolio is below my avatar. Hope we can collaborate for this project!
