Well so does mine, I was just wondering YOUR mark-up value? I am trying to compare what the average is. I know I am losing $$ for my time compared to what I would make mounting a deer for the day. If it were me I would probably charge equal to my rug cost, but that is not realistic.
I guess my whole point is I COULD have done something FUN today, like mount an animal. Instead I had to provide a service that is not fun, and is back breaking work to me.....so I question why I even bother providing that service when I never get to mount anything?

I guess the icing on the cake is when I find out my skull cleaning is now too "costly" so that "service" got dropped...
