Graduate wanting to move

I am currently entering the last year of a law degree which I am studying for at Leicester University (I currently live near Manchester). I have friends out in Zimbabwe and if it were a genuine possibility, I would like to join them. I do, however, understand that gaining work could be a difficulty once I have graduated. Could someone please clarify the realities in terms of the difficulties I would face finding any work? I have particular area of work I would like to specifically aim for, although it would need to allow for a comfortable enough lifestyle. Any guidance would be much appreciated
