In reply to Zina: I think that you need to be a little more specific and also tell us a little about yourself. Grades etc. Mind you French au pair will probably get you a thousand offers on that alone.
Be prepared to be disappointed. Sport climbing in the UK does not bear much relationship to that in Europe unless you climb in the 7's and 8's. Apart from Portland most of it is in grotty quarries. You need to get on trad to get the best out of the UK climbing scene. Good luck.
