I agree with jec - CHANGE YOUR HOURS! I would NOT do that! My hours are 7:30-5pm but most days I work from 8am-4:40ish. There is so much to do at the end of the day too that we work very long days, but my clients are allowed a 9 hour day max within my hours of business and if they exceed a 9 hour day they pay $5/half hour overtime fees. You must be feeling burned out. I don't even have to go into anything else, it's obvious to me that you need to start interviewing and find clients who fit into a much shorter day for you.
