Need Webalizer / Analytics Help

We have had to provide Webalizer stats to a business partner to show our "traffic" and they are doubting the validity of the Webalizer stats we are showing as they are very high. We need someone to analyze the settings on our Webalizer and see if it is set up correctly, and to possibly run our logfiles through another type of analytical software to verify the traffic that Webalizer is showing. I put this down as a simple project but not sure what is really involved so quotes are needed.
