I am interested in your project on behalf of my son, Rouan, who is a videographer. He (and I) would like to know more details about your project, such as exactly what sort of mobile device would be involved, what the person should say to the people he/she is interacting with, what sort of place they should be in (on the street, in a train station, in a shopping mall?) and whether what is said needs to be recorded. I have put in an interim bid, as we don't know the scope of work. As for Rouan, he has a B.A. degree majoring in media studies from Auckland University, he has a Diploma in Fine Arts majoring in photography from Whitecliffe College of Arts and Design, and he works as both a photographer and videographer. He is not yet registered on Freelancer but has carried out a number of successful projects via my account.
