Joanna, you've been here long enough to know that we don't allow discussion or promotion of named agencies here. If any agency ladies want to PM you to find out which operation(s) you're considering employing that's fine, but any names on the public board will continue to be removed.
Why don't you have a search on the punting forums? There's never any shortage of discussion on London agencies and whilst it isn't quite the same thing, you ought to get a reasonable idea whether they're a decent operation or not (and conversely if they treat punters like mugs, it shouldn't be a massive leap to work out how they treat ladies).
