I often create an "instant" CD copy for the director after a concert. What I do is take a laptop along and upload the .WAV file, do some quick edits, (maybe cut out some dead space between numbers, some fade-in and outs, and amplify the peak to -0.5 dBFS) then burn a CD with the laptop. It takes maybe 10 to 20 minutes tops to crank out an acceptable CD. That is fast enough to catch the director before he or she goes home, especially if the director knows you are making a CD for her. Make sure you get a fast card reader which should take no more than a minute or two to upload a one hour concert. All but the very cheapest card readers are fast enough, I have found.
