Poker prophecy is a big online database of sngplayers and their ITM %. I don't use it myself, but I believe the ones who do go to their website and manually enter their opponents, and then they have their ITM percentages.

From reading your post I'd also like to add that I don't think you should rely that much on the vpip and pfr rates. Of course, sometimes you'll be able to see that someone is playing 80% of their hands, and raising half of them. More often you'll be fooled by someone having a nice run of cards, or maybe old info level 5 last time you played them. I'm sorry if this was self-evident to you.
