What specifically are you looking for?
I also temped for about 3 months until I found a FAB job... and I started working about ten days after I first arrived.
One of the first things I did (actually, I did it before I even left CA) was contact employment agencies and send my cv. I worked in about 4 different places, all various industries, before I got to this one (legal).
Now for me, I was just looking for a well paying admin. assistant type job, as my 'career' aspirations lie elsewhere. I now consider myself not only lucky, but blessed, that I am where I am now. Central London, gorgeous offices, friendly, upbeat people (who do not insist I go drinking with them!), and the kindest, truest
English gentleman anyone could want to work for. Oh yes, not to mention the 28 days holiday.
So if you're looking for something generally administrative, I think the jobs are a'plenty... but
you have to go out and get them!
