answer:“Literary services” makes me think of editing. The Editorial Freelancers Association is an excellent resource for answering many questions. I lived many years as a freelance editor and proofreader and still do a bit of it. The EFA offers help in many different areas. One of the best is membership enables you to join their group health insurance plans, if you live near one of the chapter sites. One thing I learned is that proper bookkeeping is of the utmost importance. It was easy to forget who I’d done a job for, whether or not I’d invoiced them, when or if they’d paid, or a sundry other points. Also, the IRS will be very interested in the amount you get paid. In my own experience, I steered clear of offering to edit college papers and theses, because there was a fine line between my work and the student’s work. Simple proofreading is another story. Having said that, students often need a lot of help that universities don’t offer. The need is there, and someone has to fill it.
