There has to be a trade off at some point - you can’t have a guaranteed good time, for £60 for 30 minutes, with someone reliable. For that price you’ll have to pick one or two out of that criteria as you won’t get all 3 for £60.
You could risk a VS rom like Carla or Anne who have been reviewed here before, but you will likely not get OWO as it’ll likely be an extra.
My advice is to wait for an extra tenner/£20 and then you can book who you like as that’s roughly the going rate atm.
Better that than wasting £60 on a risk that might be shit - you get what you pay for as they always say
