Escort Websites - are these girls real?

I'm a newbie heading to BA. I've been reading the forum with great interest but could use assistance.

I ve been viewing the escort websites (mainly baires, gemidos, platynum) and girls seem very attractive. I know many are photoshopped, but what percentage do you think are real?

Seems like the going rate is 200-250 pesos? Is it for one or two hours?

Also, I know TLNs are not the norm, but how much would a typical TLN cost? What price would one try to negotiate?

hopefully you guys can clear these questions up for me.
