Hi!
Here is your roadmap to Wordpress freelance work:
Do the StudioWeb core language training: HTML, CSS, JavaScript, PHP, SQL
Do the Wordpress Themes course in the projects
Do the CRUDE project course as well
Start learning the Wordpress ecosystem ... know what the options are for the top themes, plugins, e-commerce options.
My Business Battleplan course will help with the freelance/business end of things.
You will be good to go.
I assume you know the basics of Wordpress.
