Help!!

I've been approached by one of my current customers regarding moving and working for them directly.

I currently work in a flight operations department near Gatwick and this customer wants me to go and work in their own flight operations, however, their offices are in Rotterdam. I enjoy my current job, but company politics are horrendous. The new job would be doing pretty much the same, working the same flight crews I deal with now, but working for a well known Oil company (Who produce Optimax).

Are there any english peeps here who have moved from the UK to the Netherlands?

Am trying to find out as much information as possible regarding cost of living/housing etc etc so that I can make a decision.

Should I go or should I stay????
