Break Even Analysis Tool Revision

I have a break-even analysis tool that I have modified for my existing project however no matter how much I modify it the original company name is on the properties of the tool. ? I would like to have the existing tool taken and redeveloped on a new Excel document so that my changes and modifications will be able to be used by me without any other company name or copyright being associated with it. I have attached the file. I always leave excellent 10 feedback for a job well done - look at my ratings and send me your best bid.
