Now this is something that takes a lot of time. First if you have a full time job, you probably need to quit it. I'm not saying it's quit everything! It's still good to have a bit of income coming from different sources, basically you just need to put yourself out there. You're going to find that you're going to work with people at your level, there's no need to stress that you're not good enough. Just tell people where you're at and be 100% honest, the best thing is to just start collaborating. Even if you charge, $20, $50 or $100 to start with, at least you're making a little bit of money and learning along the process. So chuck an ad up on Gumtree, or on Fiver, Airtasker or Facebook, put the word out there and I guarantee good things will happen! That's my quick tip of the day!
