What sorts of summer jobs are there out there for a high school teacher?
Well, that was my first thought but I don’t know if it would be right for you. Most people like to move once their kids are out for summer break and be all settled in before school starts. In New England, June, July and August were our busiest months. Properties were looking their prettiest and folks with school kids were on the move. In my Real Estate office, we had lots of teachers who received their licenses during the school year, collected unemployment checks for 3 months and racked up future commission checks. It usually takes 60-90 days for the sale to close so around Sept. and Oct. their commission checks came in. Not a bad deal in my book. Ah, we full timers somewhat resented their jumping in for the kill, but there was always enough to go around. Good luck!
I work for a bank, and one of my customers owns a tutoring business. He seeks professionals in all sorts of fields to tutor people, kids, and students (of all ages). Language tutors are the most popular, but, he says people contact him for all sorts of things. It pays well, but you also have to consider that it would usually be for a couple hours. It might be a supplement to a job instead of a full time one.
