I'm learning WordPress and I'm enjoying developing sites. However the entrepreneur in me is wondering what other services would be in demand besides building sites. Maybe areas such as securing Wordpress sites?
There are many opportunities such as hosting WordPress sites, consulting on WordPress, offering security services, starting your own theme and/or plugin marketplace, etc.
You can even niche it down further. For example, managing WordPress sites for doctors or lawyers.
Pick a niche, then pick an aspect of WordPress you'd like to specialize in (hosting, security, plugins, consulting) and go from there.
