Hi there!
I´m a photographer studying in an art school in Frankfurt, Germany. I think I could easily solve this within a few days, I have the equipment needed for a high quality photo and a few places in mind already that would perfectly match the sample photo. I also have an iphone to do it. Furthermore, I have some turkish partners in school, and one of them is a close friend, quite good looking and resembles a lot the model in the other sample picture. Also happy people and warm environment could be easily achieved. Only thing I would need to sort out is the cashier´s mobile phone reader but I have a few ideas. Please contact me for any doubt.
Best regards,
Tomas
