I need an expert in excel

I would like to link the spreadsheet to a separate workbook, (so no one knows its being checked) the following:- Month tab (eg Aug/Sept) "initials" who quoted per month Grand Total of their quotes per month Can you assist and if so how much would this cost and do you take credit card payment. I must be able to duplicate what you have done as the files will be renewed each year. Thank you in advance Paula
