I've written a CV, and I want to get feedback on it. I want to know I haven't made any mistakes, and that it's as good as I can make it.
But I don't know where to find such a service; what to expect from somebody I hire; how to find somebody I can trust to do a good job; and what to expect in terms of budget.
How should I go about this? Where should I be looking, and what should I be looking for?
