Using pivot table/chart to get top ten from various data fields

I have table with companies across in columns, months down the side in rows, and 6 parts to the data in addition to company and month. I have quotes from 3 different sources, and won deals from those 3 different sources. How do I create a pivot table/chart to analyse the data quickly, or find out Top 10 companies quoting with value and top 10 companies with won deals?
I have attached an example, taking out the company names with A, B, C, and source with A, B, C.
Is this possible? The cells do have an array formula which picks data from another spreadsheet. Which, by the way, is really slowing my machine down each time I type something into the spreadsheet. Any help as always appreciated.
