Just from using aw and ukp search functions.
External Link/Members Only has been around for ages and is well reviewed it seems. Doesn't charge extra for anal and by the looks of her profile she loves it. Not for me personally as she's a bit...'advanced' for my liking. Body seems good for her age though. Also dropped her rate since she was last reviewed.
External Link/Members Only is incredibly well reviewed here and is well under your budget(assuming A-levels are included in her rate). On the larger side of your scale at a size 14. Pictures on her profile anyway for you to judge.
External Link/Members Only is another well reviewed lass who gets her shit poked. She does charge extra so it would be your £160 limit. Again she's another well reviewed SP who is on the heavier side of the scale. Pics look excellent though imo.
External Link/Members Only is the same as the other's in that she's well reviewed, and her pics look great. Never noticed her before doing this search so I'll have to follow up on this one.
External Link/Members Only has some excellent looking tits and is spoken highly of by some on here and uke. Very tall if memory serves so if that's your thing then so is she, possibly.
It took me about 10 minutes to write that list up and those are only 5 of the most popular girls in the region on aw. I didn't mind writing it at all, but considering how easy it was I'm just curious as to how you couldn't do this search yourself?
