Uvocorp is an independent academic writing agency. They pay writers up to $ 5 per page, depending on the level of writing required (undergraduate, college, master, doctorate). If you are a newbie in the business, you will be under the supervision of a mentor, it will change your work and give you points to improve. But, for each comment, he will deduct it from your salary.
This is a good place to start and improve your academic writing skills. From my experience, the clients are students. Some of the tasks that are entrusted to me concern high school or college, such as writing a formal analysis of Carpet's page. It's relatively easy.
