I'm not really sure where to start looking.

I think we're at a point where a good manager could really do something with us (in so far as our last album got some radio play, done the odd festival, had some good reviews etc. and the few gigs we've done outside London seem to suggest there's some sort of audience for us outside of London). I'm kind of at the point where I want to push things forward and think a manager'd help but I'm not really sure how to go about getting one.

Any suggestions?
