I am going to start doing some typing/editing work for an old professor of mine in a week or two. I'm billing at $15 an hour, doing it in my free time (subject to his deadlines, of course). He is asking me to submit a timesheet every week, and then submit an invoice once a month (with total hours, etc.). I am curious if I should be following any specific formatting, what kind of layout I should use, etc. Or does the default Word one work fine?
