Now from my experience, there was absolutely nothing. Others may be able to point you in a better direction but I'll give you my heads up of things that didn't work out.
So first ahd foremost, you need to do as much research ahead of time that you can. Once you're in Turkey the government block most sites that are sex/adult related including UKpunting, you can't use a VPN to access the site either as the site blocks you from doing that also haha.
Most sites that advertise escorts are blocked and the ones thay don't are either stupidly expensive or scams.
I found a few people from sites to WhatsApp or via twitter/Instagram which is where I was told would he best to find escorts. Seems all of that stopped back in 2019 as most posts were older than that.
Recently went on a trip to Fethiye. It was a family trip, so punting opportunities were very limited, and came to nothing.
While most European adult sites (such as adultwork) seem to be blocked if using hotel wifi, I could still access blocked sites using my mobile roaming. Unfortunately as Turkey is not part of the EU, you are likely to be charged for roaming, so check before you go. There are some Turkish sites such as the below that are not - but don't seem to work outside Turkey:
External Link/Members OnlyAs the OP suggests, there seems to have been a crackdown since 2019. However, doing a search for "masaj salonu" on F/B and X produced some interesting ads. Class Massage salon looked promising, posting in March this year. However, it is shown on Gmaps as permanently closed, and only one of the numbers listed on their F/b ads worked, and the girl who answered spoke no English.
External Link/Members OnlyLikewise this ad on twitter:
External Link/Members OnlyWhen I googled the number, it came up listing salons in different cities, suggesting that the girls are routinely moving on, so I didn't bother.
The impression I got is that, following the crackdown that seems to have happened during covid, the authorities are still keeping a close eye and stamping out anything obvious. Outside Istanbul, there seems to be little punting action to be had. What little there is, appears to be massage salons offering "under the counter" extras.
