A mastering studio called The Cutting Suite is based in the UK. They master tracks for 10 pounds each, which is about $20. All you have to do is send your track to them via the internet, their engineer will master the track, and then send it back to you the same way; as this is all done online, they can master tracks for anyone in the world!

Even though their cost is cheap, they offer the exact same services as mastering studios who charge over $160 per track; they just believe in not ripping off their customers and merely providing them with an excellent service and amazing results.

The Cutting Suite has mastered tracks for artists like Jamiroquai, Justin Timberlake, Black Eyed Peas, Destiny's Child, etc, therefore they must offer a pretty good service!
