Hi Siobhan,
Is that 1000cm as is 10metres? If so that's quite a task!
The main thing with photographing artwork, particularly for print, is to ensure even lighting and positioning of the camera. At that size I think you'd definitely need to use a medium or large format camera unless your reproductions are going to be of limited size.
If you fancy having a go your self before forking out for a professional, have a look at this article:

Anyway I'm sure there's better advice out there, but hope that's some help. Anyone else have any experience to share?
