My normal search area stretches from about Swindon to Heathrow, and north south from the south coast to Oxford, always outcalls. Looking through my hot list and people I have seen (I have been punting for about 5 years), the only one I know who even remotely fits your description is Bombshell (divides time between Swindon and London). I met her a couple of years back and had a really good time (which I would expect for the price) but I can't recommend her to you after reading a couple of threads on here - she is on the UKP warning list.
Sorry, can't post link easily right now, search on here for Bombshell and you'll find the threads.
