You can set up a website, gradually build up the content (articles, videos, podcasts, etc.), then eventually monetize the site through advertising, affiliate marketing, or even the direct sale of specific products or services. Even better, you can generally find whatever services and technical assistance you need online and free of charge. Later on, when your site develops a reliable cash flow, you can begin working with paid providers who can take your blog to the next level.
As someone who's been immersed in a number of online industries for quite some time, I know a thing or two about what it takes to succeed in this arena. However, just like you, I started at ground zero with little knowledge, but a great deal of passion. What I learned along the way were some invaluable lessons from failure that hurt at the time, but helped immensely in the grand scheme of things.
