Slixa lets me see immediately the type of clientele a provider will entertain which is very important to me. It's also generally very informative and full of good details.
I have previously had an advertisement on Eros last year while visiting, but it was not fruitful especially for the VIP price. I have one up on p411 and TER are there other places I should be posting?
I've been banned from Eros for years for being too naughty (guess I said the word "prostate" one too many times)! So I never advertise with them.
I've gotten great business from TER & P411 alone on my last two visits, but those were only for two night each. This time I'm coming for four nights, so I'm interested to expand my advertising to other venues if there's something else that I should be using.
I know not all venues are effective at all price points, so if anyone has advice specific to venues that work for high-end ladies I'd love to hear it!!
Thanks in advance ladies & gentlemen. 
We would also like to know since every city is different.
Thanks

I have only ever consistently used TER and 411 and am busy enough.
I had extra income several months ago and instead of booking another shoot I booked a 3 month ad on CS.
I do not believe I got ANY inquiries but then again I have never bee THAT busy in LA which I attribute to the huge volume of girls who share characteristics with me (blonde, thin, white, younger, etc et) so I don't really stand out.
To asgoodasitgets: what research does CS offer? I thought it was just an ad site? Or do you mean to compare rates/photos/etc? Makes sense because there is a girl (or maybe more than one but one for sure I know of) on there who is 100 hourly lower everywhere else. So it pays as a hobbyist to shop around and not just use one site when looking into a date.
The same clientele who browse CS also use TER, so I wasn't reaching new markets. Moreover, there have been a slew of fake pictures or ads on CS recently, and I don't want to have my reputation/authenticity questioned. If I'm paying those rates for advertising, I would expect the site to better curate their ads.
In my opinion, you do stand out+++
here is a great number of ladies on there so it might be worth posting there if you aren't on the west coast typically. The link there might get noticed if the ads here didn't. It could also help legitimize you a bit since you are touring and some ladies post touring ads but then change their plans or don't go or whatever. The admin there might work with you depending on how long you need/want your ad to run so I suggest if you still haven't found other forums to post to contact there and maybe see about if there are touring rates or a way to determine the number of clicks you get there? I didn't ask that for me (I'm sure the data is somewhere but IDK how that can be found there or other sites with multiple pages, maybe the sites tech people have an easy way to see and could see if the ad got interest after if you try there?)... Doesn't hurt to ask
Side note:
I wish CS didn't open every other link in a new tab.... It's really difficult to navigate upon trying to brows the site just now.
I noticed many new providers post ad on CS before they have review or joined P411 so it's worthwhile for me to research there for new providers. There's also many touring providers who post there. Since it's free for me, I check there to see if I missed anyone who I like to meet.
I usually don't book touring providers because our schedule wouldn't have worked or I find out too late (I already made other arrangement).
you ABSOLUTELY stand out ! 
I've used this as a source in addition to the ones you mentioned. As with TER and P411, a basic ad is free and they options to upgrade your account.
Sliixa got me some emails however, I think they might have actually been people working for sixla. Nothing panned out.
The way I reach out to a lady of interest is either through a direct email or via P411, depending on the situation. I use Slixa, CV, CS, Sugar Nights and a few others, along with P411 and TER to narrow down my search and to validate.
I would say this, if it's free then leverage it. It's not costing you anything to have a presence on the site regardless.
Just food for thought.

My Opinion, May be wrong but this is what I think. Your phone is not going to be ringing off the hook at the rates that you are asking. Not too many people can afford that and for those who do,,, there are way too many options.
