A webmaster forum is not the best place to ask, nor is a free online resource the best to use.
You need to speak to a lawyer. Well worth spending a couple of hundred bucks to get it right.
Using anything "free" or copy/pasting from another site could leave you exposed.
Part of the WebmasterWorld TOS disallows discussion that gets into legal terriatory for this very reason.
