This might be a stupid question but figured I’d ask:  is there a site or place where you can find UTR providers?   I know a site might defeat the UTR aspect so I don’t mean to be dumb, but I was wondering how or if there were ways to find some or learn about them. Or do you just have to ask a bunch of other providers until you get lucky?  
Thanks for any info.  Open to PM if people are more comfortable with that.   Thanks!

That's not a simple definition.  

UTR can mean that they're only available through a booker. Usually this is how pornstars operate. Sometimes they're on sites like theLuxuryCompanion which I find to be a little suspect, but other people vouch for them so they're probably legit. Other times they're going through a local agency (sometimes under an alias).

 
UTR can also mean that they've taken down their site/ads/ter profile/etc but are still seeing their regular clients. Again, sometimes they're still available if you know who to talk to or if you've seen them previously. I'd be very sensitive going after this kind of provider, because it probably means they're trying to keep in on the DL for various reasons (sometimes legal).

Generally speaking, ladies that are UTR are ladies that used to provide publicly, and only see former clients or someone by referral only (i.e. a provider friend's client if she is out of town or sick).  

For another idea, you may want to reach out to Andrea Sugar for an UTR recommendation. There's a nice thread about her below a little bit, with her email address.
