This is the sort of thing likely to "burn" people; if it's a legitimate MP, they can't legally offer full service, and sharing this sort of information around is liable to get all sorts of people "burned." We could sum up by saying that a MP that offers full service is likely to be viewed, by the law, as a "common bawdy house," and that's simply illegal. (And takes us to the "I'm looking for your sluttiest whore!" thread...)
If you want "full service," then you should simply search for escorts, as that is frankly likely to be a cheaper, more satisfactory, and less risky approach, overall.
Visiting the Escort section is highly likely to be more satisfactory.
