In regards to the job market, you should check websites with advertisement for legal positions, or give a call to agencies and ask them directly.

As for coming to the UK now, I think it is getting harder and harder, there is a nasty strike in recent British politics where foreigners are the scapegoats for all kind of ills in the country, thus the government is acting in consequence, not to mention the economic situation is pretty bad, nevertheless if you manage to find a job you should be OK.
