Graphs based on 5 Excel tabs (3 columns of finance data)

I'm looking for a freelancer to help me generate line graphs based on finance data stored in 5 separate Excel tabs. The graphs should emphasize a few, specific data points as specified by me (columns c,g and I) then put on graphs tab. My preferred format for the final deliverables is an Excel file. With your expertise, I'm confident that the data can be presented in an effective, graphical format that will help make individual trends and relationships clearer to my team.
