I lived in Singapore for 8 years so if you have any q's pm me and i'll be happy to answer.
Its a small place and easy to learn your way around. I'd also say that 90%(this figure is taken out of my **** but should be pretty accurate) of the general population speak english as well and if not english than certainly singlish, i'm sure you'll figure out what i mean by singlish when you get there. So if you can speak english you shouldn't have a problem.
Now did you mean p4p or actually pick up??? There's a misconception that singaporean chicks are prude because of all the strict laws in singapore, i assure you this is not the case. For p4p you have places like four floors (orchard towers, geylang and descare rd (spelling could be off). Maybe more that i don't know about. But these places can be a bit dodgy with the exception of four floors, which has chicks from the Philippines, Thailand, Viet, Cambodia, Malaysia, Laos and china. Last time i was in there was about a year ago and the going rates were S$100 ST and S$200 LT.
Besides these places there are many places you can go to pick up. Boat Quay (many bars and restaurants), Mohammad Sultan (lots of bars, try a place called "next page" used to be a good place to relax and chill out, Clark Quay try "ministry of sound" and "Gotham" and "Attica". Attica is my personal favourite. Drinks on clark quay go for generally anywhere between 10 - 15 singapore dollars and can get more expensive for cocktails. Generally $12 for a beer or mixed drink i.e vodka soda, whiskey coke. Singapore has gotten more and more expensive every year if you ask me. There are some after work bars on emerald hill, and if you like nice little bars with great atmosphere try the Alley Bar on orchard rd, right next to centre point shopping centre. Near alley bar is a night club called Rouge which is also not bad. Good decor and atmosphere as well, but only on friday and saturdays and some thursdays wouldn't recommend it any other day. Hope this helps.
All the best for the new chapter in your life:cheers:
