Graffiti Artist Wanted

A catch-all forum for urban discussion. If it doesn't fit elsewhere, post here.
Apologies if this is in the wrong thread. I'm fitting out my office space and need a recommendation on a graffiti artist to do a mural on one of my walls. Would anyone be able to provide a name for me?

Thanks!
I'd contact The Screwed Arts Collective. It's a loose group of young artists doing exactly this type of work. Lots of pics on their website:
