Okay, let’s calculate this. Jessica has a solid education from the University of California, Davis - School of Law, which is a reputable institution. Her skills in editing, proofreading, and writing are in demand, particularly in the legal and publishing industries. Given her location in West Sacramento, California, the cost of living is relatively high. Considering her education and skills, I would estimate her hourly rate to be around $75, which is a reasonable starting point for a writer and editor with her background and experience.
