LLP - I’ve been punting for 20 years plus, so yes, I know a bit about the hobby.
If you read what I write carefully, I said I couldn’t find anything half decent. That’s a subjective opinion. London may be the biggest SP market in the UK, but that doesn’t mean there’s anything of quality at the right price, with SPs from £79 p/h to £500 p/h plus - most with very little indication of what you’re actually getting.
As for your rather accusatory questions - I used google and typed “cheap London escorts” - go down far enough and they show up.
Thanks for the details, and if you carefully read my reply this "how is it that you genuinely believe you can open a thread claiming you can't find a suitable SP in London" is the key serious point, (the rest just ragging you).
So the pertinence of your reply is "cheap London escorts" which kinda reduces the market size considerably, perhaps not by volume but certainly "quality".
You have failed to remark what "quality" means to you so again we can't help, apart from well intentioned blind suggestions. You could be into "cheap" 3'6" miniatures with odd sized tits, gonads and a mohawk.
Perhaps specify more clearly what you fancy/floats your boat and some of the encyclopaedic todgers here will have a few they can point their wangs at.
