I'd say almost every one on earth understands the universal hand gestures for hand job (one hand in a fist, moving up and down) and sex (one index finger going into and out of the ring made by the thumb and index finger of the other hand). BJ is pointing to your mouth and saying "OK?"
Further,

means okay in Hong Kong, it's not rude.
Crossing your forearms into an X (like 'no goal') works for no.
Since you can't speak Mandarin or Cantonese, trying to arrange an appointment probably isn't worth your time. If you're going for hotel girls, the guy that books you (papasan or PPS, mamas an or MMS) could speak English, but doesn't really care if you're going to fuck the girl or watch television. You pay your time and negotiate inside.
So, in the end, show up to where you want to go. Knock on the door. You can say "OK?" and she will say "OK". Then you go in, strip, shower. She will put you on the bed, lick your nipples, cap you and maybe give you a condom blow job (CBJ). If she tries to go further, you can move your body away and point to your mouth or make the hand job gesture. Profit. Most of them would rather do manual labor than have sex anyway. Wouldn't you like to do less work for the same pay? I would.
Charges won't be less for less work, keep in mind.
