Data Entry / Report Creation

Hi: I need someone to compile two sets of search engine ranking reports into a specific format that I will give you. There are 6 clients total and I need a report that shows their current ranking, past ranking, and the change between the two rankings. I will provide you with the past rankings and the current rankings, all you will need to do is plug the rankings into a new report and calculate the difference from the previous month. This will be a very simple project for someone experienced. THE SOONER THE BETTER. I would like to have this done today (it's morning in the eastern US), so I will be picking the first, best bid. Please include when you can have this finished in your bid. Thank you.
