Many websites need part-time writers. Examiner.com pays people to write reviews for restaurants, shops, parks and concerts in their area.
If reviews aren’t quite your thing, ProBlogger has listings of sites that are willing to pay semi-professional writers. Over time, good writers have found this sort of freelancing can be quite lucrative. Every website has a different application process, so log on and get paid.
New tech products are hitting the market every second, and someone needs to explain how they work in plain English. Technical writers put together operating instructions, how-to manuals and FAQ pages for consumers. Consider joining the Society for Technical Communication, which provides educational webinars and a job listing board to members.
