Here is a video posted about 8 months ago by Asian Tinder who was walking along Sukhumvit from Asoke to Nana. He asked a number of freelancers (including some ladyboys) prices for short time and long time. You need to keep in mind the inflation factor in Thailand is just like in your home country, the cost of everything has gone up - so don't expect prices of 500-1000 Baht for ST, unless they are in a desperate situation.
