We're all 'entitled' to legal advice. Like the Ritz Hotel, the law is open to everyone.
If you really think you need a lawyer (and if your complaint is simply a dispute about facts, rather than some complex legal issue, you probably don't) then see a lawyer who specialises in the area of law appropriate to your complaint.
I should forget about taking on 'the establishment'. If a specific person or persons have wronged you, then concentrate on what you would like to be done about it. If you're just angry and want to make a stink, have a rant on PPRune instead.
