Well I have a three month notice period (leaving after two, agreed with current manager) so I started sending out CVs as soon as I handed in the notice. Then last week I started hammering agencies and clients directly, letting them know when I'd be available, setting up weekly calls with agents for updates etc. I don't have a network of contacts I'd call sustainable yet, but hopefully in about a year I'll be there. One piece of advice that I was given was: Re-write your CV in the style of a contractor, not a permanent member. Think this has helped quite a bit. That and I'm on agency sites most evenings, making calls as soon as I get home from work chasing applications etc
