Expert Excel 2007 Trainer, Leeds UK, 29 June

I need someone to teach an Advanced Excel course on 29 June in Leeds. Full agenda attached. It is a pretty packed agenda but it is for only 4 people who are reasonably proficient in Excel anyway, so it is hopefully possible.
Looking for an experienced trainer who could answer any questions on Excel from a knowledgeable audience. In particular some of them are likely to want to know differences between 2007 and 2003, in regards to the subjects being covered.
