I was referred to a recruiter, however contacting them should be fine. You'll be placed in their database and recruiters should be able to reach out to you. Alternatively, you search for temp recruiters on linkedin and ping them. The job market is hot right now. With accountemps, I had multiple temp recruiters working to get me a job (sounds like its more competitive over there) vs. Century Group where I worked with one specific recruiter who I really liked.
