A friend who does this says that she charges sliding scale $125 - $150 / hr, which seems like a lot to me; I usually figure my class rate as around $25 / hr / student. (She's comparably published to me, although in somewhat different areas.) I guess I'm having trouble figuring out how to scale it appropriately. Any thoughts on how to approach this? I find this whole process confusing and stressful.
I also hate pricing my artwork. And negotiating salaries. Same problem. Is this a gender thing? Or do guys hate putting a price tag on their work just as much?
