Not to step on Mt French's toes, but being verified with Lita I can confirm how this works. Note that I have never used Lourdes to book an appointment.
I paid nothing to get verified. It was not a painful process. I got to speak to Lita on the phone during the process, which was treat anyway since I was a fan of hers back when she was in porn.
After being verified, I was sent a list of her roster. It was broken down by location (city). This included some who had an "UTR" designation. It did not include rates. PLEASE DON"T ASK ME WHO IS ON IT. I WILL NOT TELL YOU.
This was before she started the "Untouchables" thing. She made it clear that were others who not on the list for various reasons and if I had anyone in mind not listed to ask. She also told me that if I wanted to access her site, I could put down a 1k deposit that could applied toward my first appointment as long as it was within 60 days. I passed on this without even asking what the benefit of site access would be. I don't live in a place that gets a lot of PS traffic, so the 60 day clause was not going to work for me.
Since then I have asked who's available in a specific city when I've traveled. The answer has come in the same form as the full list, but only the portion for that specific city. Since she started the "Untouchables" program, the city list has included the word "Untoucheable" in bold letters. I GUESS that means that one or more of her "Deep UTR" ladies are there.
I assume if I ask for the full list she will give it to me. That is an assumption though as I have not actually asked.
So unless it's changed in the past year, you can get verified and access to a somewhat complete roster list without paying a dime.
Hope that clears up the mythology of Lourdes UTR list.
Mr French is absolutely correct that you can find lower rates elsewhere. I've compared their rates with both TLC and Helpubookher and found those two to be much lower.
