For a job like this I charge 40 an hour. A one color job of 100-200 would take maybe 2 – 3 including cleanup, so I would round up to 100 probably. I charge per print if I have to do all the incidentals like ordering paper, cutting paper, prepping files, getting plates made, setting up, ink mixing, printing, re-trimming to crop marks, and shipping. That way I can be sure to charge for all that extra labor. If you are just printing and handing off, Id say do it by the hour.
