How do you figure out what specific amount for a startup fee is charged for a particular IC?

Question is regarding E&O insurance. I understand you provide this. Does that mean I can be a sole proprietor or is it still best to become a LLC?

How soon after start up fees are paid can a new TA expect to be qualified to book their first vacation?

Will the study materials clearly outlines the journey a newbie will take in order to feel qualified to call himself a TA?

Will there be testing to determine if the study material is clicking for the newbie?
