Don't know the exact figures but when i visited Singapore, i paid for a modest hotel room around 150$ per night, pack of cigarettes ~ 5-6$, price for whores ~ 100$, after negotiating from 200 with everyone.
But the MCD is very cheap, eating with 3$ a good menu.
Regarding porn i don t know but the real, not the virtual sex industry, is very developed

Had a great time, a great place where you are really feeling safe all over around and at every hour of night.
I will come back there anytime, beautiful women, the weather is warm absolutely in any period of the year.
P.S: I would advise not bringing even 1 gr of weed with you, the death penalty will wait you for a very small quantity of any kind of drug.
Also electronic cigarettes are illegal, the airport guards had confiscated them immediately after checking my luggage with x rays
