Having done your research you know that your 120 limit shuts you out from all the "reputable" agencies that have reviewed girls here.
Recent reviews reaffirmed that the cheaper outcall only agencies for under 120 are scams. Most are "EE" so in this sub-cat consider them criminal Roms/Albanians/whatevers.
As you've rejected all recent reviews (how far back did you go?) you've already discounted Jonestown's suggestion, despite it's promise, presumably because she's EE.
You're down to TOFTT with a rare(<120) unreported English newbie off a listing site or going to a massage parlour.
For the latter you can either take the intel you've already reviewed in the massage mini-threads to id some establishments and then TOFTT on a girl not mentioned or reconsider one that has. There are dozens of places and more girls scattered across the metropolis, just choose an area, rock up and have a sniff.
Given all your constraints so far are there any others? English Caucasian? Afro-English ? Any-English? Anglo-saxon? Celt? Body shape? Tit size? Hair colour? Depilated? Tall?
