I've looked at Upwork or Fiverr, but they didn't knock me out.
Agreed: Upwork are actually quite difficult to get accepted for. Fiverr will take anyone from what I can tell, but the issue is their cut. Once you work out what you want to make and adjust prices accordingly, the platform itself is very good. I've only done two jobs via Fiverr but both went smoothly. I've also used Fiverr as a buyer to get some tracks mixed and mastered, and have been extremely happy - I did spent a lot of time vetting people though.
