Would you need above info instantly or would you be fine waiting like 10mins for the results to arrive? Also, would you be willing to pay for it ?
The 10 minute wait is only ok if the result is really really good. If I use google I do maybe 15 searches to crack a mildly hard nut, if each search would take more than 10 seconds I'd be too annoyed.
I would pay, but again it would depend on the quality and I would probably use it just once a week. If I could do it myself with google in 20min, I would not pay more than 2 bucks. If you can do the china-shop thing, I might pay 15 or even 40 if I knew it was good.
When I search for myself I get a feeling for whether there is more information out there or not. I'd have to trust the service to be good enough not to miss much.
