There’s plenty of work and clients to be found. If you know where to look. To start, you need to know if there is enough demand for your skill to make it worth the effort to go out looking for work. Start by searching for freelance postings on sites like Flexjobs, SolidGigs, Contena, greatcontent or one of the dozens of other skill-specific freelance job boards.
Then once you’ve got your domain name and hosting sorted out, it’s time to pick a CMS, or Content Management System, that will let you update pages, build your blog and integrate with all the other services you need. It’s hard to go wrong with WordPress—the CMS powering close to a quarter of the internet. Keep in mind that eventually as you start growing traffic to your blog, you'll be wise to invest in a managed WordPress hosting plan from a company with great service like Kinsta, where all of the settings are custom-tailored and optimized to work particularly well with WordPress-powered websites.
