Cameraman needed to shoot roaming interviews at London Event - June 4th

I need an experienced, confident cameraman to shoot a series of 4-5 minute "roaming" interviews at an industry event in central London on June 4th. Interviews and guidance to be provided by the client on the day. Person will need to provide all required equipment, including high quality sound recording (tie mic) and camera top lighting. Filming required in HD and footage to be delivered on solid state memory (SD card?) within 24 hours. Event will start at 9am, finish at 5pm, filming will be sporadic throughout the day. Budget £200

Please state the camera to be used for filming and the recording media. Thank you.
