[Histonet] Frozen section case "charges"

[Zajic Kari]

Hello all Histonetters! 
I have been asked by a pathologist to do occasional skin frozen section cases and was wondering what a fair "charge" for my services would be. I do not have to travel nor process the cases, just assist and cut the frozen section. Should I be charging per block/frozen or per case? They only take approximately 20-30 minutes to do according to the size of the specimen.  
I would appreciate the feedback, especially from my fellow techs in Florida...

Thank you!

Kari
