Since my first phrasing of the question seemed confusing, I rewrote it:
I'm looking for copywriting websites where copywriters can sign up and people who want a copy written can sign up as well. The website works as a mediator between two parties, making sure the better copywriters get the more expensive jobs and the lesser get lesser jobs.
I know these websites have a certain name, I just can't seem to find what that is. But I'm very sure they exist since I've been on them myself.
As for the experience, I have written copy for some companies I'm associated with, just for the practice. So I do have experience, I'd just like to smooth it out and see what I'm up for before I truly start showcasing myself. Learning and doing (for real) at the same time is 5x as effective in my experience!
Thanks in advance,
