Hello, Ashley.

You want to have a better salary? Well, that depends, in most cases, on you educational level and your labor experience, most of high paying jobs hire only highly qualified employees, regardless of the business field.

So, EDUCATION, that is the key.

Cheers

There arn't rules for this. Going from low-paying to high-paying jobs isn't as much of a jump as it as a gradual climb.

You need to build confidence in yourself and your work, and get a good understanding of the marketplace. And when you're read just gradually starting raising your rates and looking for bigger jobs.
Make a mental commitment to freelancing for higher-value clients! Good luck!
