Phil, I can empathize with you about the time that your jobs take up, especially teaching. My sister teaches 6th grade and she literally works from 60 to 70 hours a week and then has to grade papers, etc. at home on school nights and weekends. I have always said that teachers are worth every dime they get.
Post some pictures of your shop when you get the chance. Virtual tours of other shops are always a welcome post.
