Just had a great two day workshop using Hasselbalds with Olaf on Maui, Hawaii. Very knowledgable about the camera and the area. We worked with compressing some scenes with a 500 mm lens and scenic landscapes with a 40mm and a 50mm. Great mentor and very reasonable. I got in touch with him after seeing his workshops lsited in Shutterbug magazine. He is at EVERAFTERMAUI.com He usually teaches Nikon and Canon workshops but he will contract with you for Hasselblads. FYI, rates on hotels, etc are all down right now in Hawaii so you can get great deals on rooms, food, travel, etc.
