instructions on the various websites & be Polite, Patient & Persistent.  Good luck!!!

"Getting in contact" is usually not the same as requesting an appointment.  Bookers don't like to chit chat unless you're spending $5k a month with them and they don't like time-wasters.  Format your request properly and you should get some kind of response.  If you don't have all of the required information they usually want with the initial contact, you usually don't get a response because they know they're going to have a back and forth exchange, which wastes their time.  There have been many discussions on this board within the past year about the proper way to make first contact.  Do some research.  

I sent response as well.  I think it is like LA a bit - hard to crack if you are just passing through.  Much easier in NYC than here.  I still cannot get into LA easily.  I would recommend phoebe and nabiki as Indys.  PL being number one even over an agency IMO.  nabiki is great - but a little hit and miss. Some days - she just seems completely out of it.  Hard to explain. Stephanie - great but better for people that can be repeat so she gets more open and less business like.  

The Thai agencies I heard are good. Have not visited yet but follow Kgirl script.  Full GFE experience.
