I make $60/hour through an agency. I do this for 20 hours a week.
This is in addition to my full-time gig.
Assuming I'm booked eight months of the year, that's $38,400.
I could make more if I wasn't going through the agency, but for now, I don't have a name or connections, and I don't have the time to market myself.
So I figure do the agency thing first, build a name, then start soliciting direct clients. Then eventually ditch the full-time gig.
Honestly just stumbling through this.
