I dont't know about others but for me, 1st red packet, i gave $30 and the 2nd red packet, i gave $50. She came by herself, it was already agreed initially. I didnot pay her other extra stuff. I took care of her meals and sleeping though and helped her to buy phone cards. Coincidentally, was sharing among some friends, these CLs tend to have many phone calls. I bought about 3 phone cards for her while she was here. She was quite considerate then, never use the phone when babies are awake. Only used them when she is resting, so this is one point you may have to be clear with them.
