8. Proofreading and editing
You would need some time to get your first client because there are many people offering this gig, but there is real potential to make serious cash. You can work for $5 per 1,000 words on eBooks, blogs, articles and other similar writings. The jobs can vary – offering content, grammar and spell check (you’d be surprised). Many freelancers use software to check spelling, so if you show any more effort than that, you can expect better reviews and more frequent job offers.
