I know this won’t be a massive help to you, however there was a disabled guy who posted on here about 18 months ago. Everyone pretty much thought he was trolling, but he was given the benefit of the doubt and the advice was post an SS ad on uke.
He did that, and got a couple of responses, he met someone and reviewed here. It was in the London area (not sure if south). Honestly I can’t remember his name, I did look here and on uke after I first saw your post, alas I couldn’t find anything. I even looked in my messages as I had sent him a PM because his username here and on AW matched and looked like or was at least similar to a ‘real name’, but my inbox/outbox doesn’t go back that far.
So my advice would be post a service seeker advert on UKE.
(Include services required, budget, type/age of escort and a general area)
Good luck.
