Reply to 'DN4 DJ's' - Anyone had any expiereince of working with these guys?

Just been contacted by this London based DJ agency about the possibility of working with them.
Their site seems pretty genuine (if a little short on content http://dn4djs.com/).
They have asked if I can give them a call today, but before I do that I was just wondering if any of the DJTT community have had any experience of them?

Any insights would be appreciated!
