Hello there, can anyone tell me of any good websites to find jobs on?

Preferbly jobs in London as I shall be moving there in September which is when I'd like some employment.

I'd like a job which utilises my degree in Psychology in some way but I'd also like to be working in some kind of sector which involves working with vulnerable people such as children or the elderly. All that kind of experiance will help me for later plans.

Failing that some temping places.

Also because I'm lazy I'd like some advice on how to write a CV as I haven't had to do one since I was in school!
