Probably the least expensive option is using AI content generators. Many of these sources are available free on the internet, but they have major drawbacks. The content you receive will often seem awkward and stilted and may even have incorrect grammar, so you might spend time rewriting the end product. Working directly with freelancers can cut out the middleman cost, yet at the same time, you may not get the quality of work you desire or even get the work at all. Contracting agencies will put a premium on top of the freelancer's cost, but you might also have to pay for other services that you don't necessarily need. The price you pay for freelancers, no matter where you go, will depend on the writer's quality, experience and specialization. Expect niche products to command writers with high prices. Platforms like Textbroker will give you the best value for the money as you can select writers based on specialty, experience, level of quality and more to guarantee that you get the results you're expecting. You never have to pay for work that doesn't meet your standards.
