Catalogue Design

We are a mail order catalogue supplying the UK's Day Nursery sector. Our current catalogue is 324 pages approx size A4 (slightly larger). We need an extremely imaginative designer who can think "out of the box". He or she would be based in our office in Derby. Previous catalogues have been created on a Mac. This is not for an internet based catalogue but for a 42000 print run.
Timescale: starting on September 3rd 2012 this would be a maximum of 14 weeks contract (or less) but must be completed before Christmas 2012 with all print files being ready at this time.
Payment would be at the end of each month.
