Another option for freelancer, is to get contacts directly from massage shop girls.

If you walk along Le Thanh Ton @ Thai Van Lung (around Little Tokyo) you'll see the many massage shops geared towards Japanese outside asking you for massage, and grabbing your arm.

I talk to many of these girls, and get their contacts. Many of these girls are willing to go to your hotel if you appear well mannered and decent. I got two contact late at night, and they were willing to come to my hotel for around 1M. I never took there offer, but kept their contact as backup if needed.
