Good dyno operator in Denver area?

I'm going to install the Dinan throttle bodies, change the diff to a 4.10 and install an Active Autowerke muffler set next month. I'd like to do a before and after dyno comparison and would like to use someone familiar with M3s. Does anyone have a recommendation?
