Hi, Rashomon
$60k per year is average. Definitely, around 25%-30% freelancers are making more the 100K per year.
Rashomon It all depends on the skills. If you have experience ( around 3-5 years) and skills, just go for freelancing after building some contacts.
Keep one thing in mind in freelancing you will earn more than a regular job. It's just a matter of getting clients.
Please let me know about your skill level and experience surely I will help you with other questions.
