Hi there,
Very envious, how amazing, what memories you will create. I do a lot of corporate explainers/ animations and corporate videos, but always enjoy interesting projects, like this sounds! Can give you plenty of corporate links, depending on what styles etc you like..but perhaps a recent long 70th birthday tribute will show you a better indication. For this project, I did each section different style, and audio etc was personal and relating to the recipient.
I believe that great communication works best for both to get the end product right. I provide plenty of samples for review/checking and comments/changes along the way and value feedback/critique to make the end product better. The quicker we are on the "same page", the quicker the end product is perfect for you!
