The worst motivation for starting a business is the need for income. A business has to be built over time based on meeting a market need. Of course a business must make money to be successful, but this can take a bit of time.

So, the real need is to use the online world to make money. Based on your copywriter skills, here are some ideas to get you started:

1) Start a blog. You can do this for free with platforms such as Blogger and WordPress. This will provide you a chance to show case your writing talent. Writing articles about copywriting can both demonstrate your writing ability and be used to market your approach.

2) Join job markets. There are several freelance sites you can use to make extra money without little to no cost, such as Upwork and elance. You will find jobs on these that will help you earn money and build your portfolio. The pay can be low as the markets tend to be aggressive but a few good contacts can lead to a better source of work.

3) Build your network. Connect with people who provide web marketing services. They need guest bloggers, ghost writers and ad copywriters. Over time you can build a steady source of freelance work.

Once you have a good portfolio and practice, you should consider building a branded web site. But first, build your freelance brand. This approach works with other skills too.
