what are the chances that her attorney will be able to have the second charge changed to a different charge or plead down so there will not be two convictions for a 647b and a 45 day jail term.

she  is independent and she was contacted by phone by a couple who said that they were from orange county and in la for the kings game and were spending the night at a hotel downtown.  they were really undercover cops and she went to their hotel.  when she got there there was a brief discussion and a couple minutes later the cops swarmed in and handcuffed all three of them and separated them and later came back and told her that the couple rolled over on her and told them why she was really there.  they also said that they were monitoring the couple's internet activity.  she told the cops that she was not contacted through the internet.  they took a picture of a condom she had in her purse and her vibrator and pretended to ticket the couple as well and let her go.

Just do a google search for "Los Angeles Prostitution Lawyer" and you will have a bunch of search results of lawyers who specialize in these types of cases, then start making some calls.  

Any decent lawyer should provide you with a free initial consultation for half an hour or so, in order that you can decide whether or not to hire them.  They should be able to answer your questions and tell you what they can do, and how much it would cost.  Some may charge by the hour, some may charge a flat fee to handle the case.  Talk to a few different lawyers and then pick the one you are most comfortable with.
