Music artist biography

We're are a small label based in London. We have just signed a very promising new artist and need a smashing / captivating bio written for PR / social media. The artist had some decent success on X Factor in Germany but we don't want to stress on it. We're preparing for a single release campaign at the moment and so the Biography should be ready before the campaign starts. We already have some base bio written, so it can be worked with.
Looking for very creative writers. Experience with Music artists is of great help.
