Ask HN: Can you share advice on creating a Web Development/Consulting business?

Hey, everyone! For the past several years I've been learning web development(Django, Node, React), internet marketing, and building my portfolio. Now I think that I'm reasonably good at this stuff, and want to use my skills to create a web development/consulting business.

I want to start small, gain basic business skills, learn to work with clients, and gradually grow it into a big and successful business.

Can you share some advice on getting started? Are there any great learning resources that may help? How would you recommend to look for my first clients?

Also, I would be really grateful if you could look at the landing page [1] that I've built, and let me know what you think. Does it look good enough to show to people? What could I do better?
