It's time to move to the countryside, away from the hustle and bustle of a city. Mind you he may have to suck it up and pay the money if he can't move shop fast enough or fine other temporary arrangements. I liked how he felt that he was tattling to the teacher by running to the City Lord. While I 100% agree with that opinion, he may not have any other viable options in the short term. He still needs more time to get his new site up and running. At this point it's quickly check for any other viable options and if that fails see if there's any way to reduce the amount he has to pay. Then leave the moment you're capable of because this guy will definitely take the Darth Vader approach to contract negotiation.
