Camera operator with own kit to film a music concert

I am filming a relatively small music concert next weekend 27th July. I need a stationed camera perhaps back of auditorium to film the artist. We will also record a pre-concert interview with the singer. You need to have your own kit (Camera and tripod) mainly but light will be a bonus too. Location is in North London Area. It will be around 3-4hrs that you will be required for from around 6pm to about 10pm. Ideally I will need it film in digital format i.e Flash card, hard drive etc so I can grab digital files off you after. We want HD filming so not really looking at DV tapes. Ideally 720p or 1080p are fine. Please specify what camera you will be using. Thanks!
