come to America 
no seriously though, I don't know how girls behave where you're at. However, the ladies you just described are indeed few and far between.
- sexy flirty talk : some girls like it, some girls don't. Ladies usually welcome it when the guy is fun and attractive (score!). If some ugly drunken fleabag tries it, the lady gets disgusted. Nothing too graphic or gross tho! You probably know the art of subtlety 
- touch her in the right places (down boy, not THERE <yet> ). A gentle touch on the shoulder, inner elbow, middle of back. She'll usually respond with reciprocating the moves ... sidling in closer to you ... or a slap.
- don't get drunk. That way you don't end up with some ugly hootch stinking up your sheets in the morning.
A trick I like to use is to speak a bit out of hearing range while looking directly at the guy I'm interested in (eh, usually soft spoken anyways). That way, he'll have to move closer to hear what I'm saying ... and in louder places, I'm pretty much whisper-talking into his ear (rrowrr), and I can put my hand on his shoulder while doing that ... applied with the "barely there perfume scent" leaves him leaning in for more. 
Though best way is to get to know the girl and gradually work your way up to a relationship ... just don't fall into the "good friends" trap!
Good luck!
