Ok, that means you have to build a reputation and figure out how you can bring value to your customers lives. I suggest looking at Louis Rossmann’s early YouTube videos for how to build your business’ reputation with your customers (aka creating repeat business that recommends you to their friends). As that path will require you to seek out how to improve your services and your skills and the appropriate help when you start approaching success.
Ok; you need to get comfortable with the following pattern. Database queries that produce a single JSON that you then stick in a hidden read-only input. That you then use to generate the webpage and its expected functionality. Then any button press is either self-contained to the JavaScript working on the JSON data or creating/updating/deleting something in the database that can be passed. That is all you need for 95% of all business websites.
Then you’ll spend most of your effort on the JavaScript page behaviors and the css tweaking that the customer will value more than everything else.
Beyond that, there is the question are you seeking a job or creating a business?
