Financial Analysis

I am looking for someone who can assess up to 4 spreadsheets to identify underlying differences that are affecting headline figures. These spreadsheets provide a breakdown of various figures associated with the card payments industry (processed sales, interchange, scheme fees etc.). Essentially we are looking for someone with a very, very analytical eye that can report back on the reasons for fluctuations between key measures and provide more detailed insight.

I expect the analysis will take 1 day but if more work is required, we are happy to consider more time.
