How do you know when you are being proposed a good service?
Are they alone?
If they fall ill or go on holiday they can hardly help can they. If they take things on personal experience how much experience have they really had and how varied is it? Did they just 'get away' with a bad job because no one knew better.
Do they have a global view, I mean, your best interest at heart for your family, work and home?
Do they take intro account financial, social and integration needs?
Because unless they have a law, accounting and mobility degree, how can they really advise you?
Rest assured, its as much about advice and guidance as it is filling in the forms correctly.
Its about planning, resourcefulness, tenacity, diplomacy and charm all rolled into one.
Good luck getting that all rolled into a one man band.
