Greetings all, I charge $75 to show up at site as well as setup. As most my jobs are one day or less, this works fine. However, I am know on day 2 of a 3 day job. The site is not safe for me to leave the unit there over night. What would the consensus be on charging a setup fee for every day as I need to bring the machine back and setup for every day, or do I charge once only. Each day has been a full 8 + hours. I don't want to over charge, but the amount of work is the same as if I were to go to a new site every day. Thoughts??
