Hi NG, if anyone who is qualified or thinks they arereally good at mastering and mixing and such, I will pay 20$ to whoever will do it. The song I have made is done, and it just needs some engineering before it becomes a top notch song. The demo can be heard on my audio page (latest song). Email is email@example.com. Thank you everyone!
You should try and learn to master your own tracks. You won't learn if you have people do it for you. Try buying a mastering VST such as Ozone 5.
You can learn more about it here: http://www.izotope.com/products/audio/ozone/
Follow some online tutorials and just experiment until you get mastering down.
