where can i buy targeted twitter/facebook updates?

i remember coming across a couple of sites that let me browse what profiles were selling twitter/facebook status updates and their prices but cant remember what it was. Anyone know?

I konw i can purchase updates on fiverr but i'd like a way to browse the different prices/pages/profiles so I can specifically target my niches. Anything like that out there?

I know a few people here are asking how much they can sell accounts with 500,000 followers and what not. Maybe you can give them a message and see if they're open to promoting what you need. It will definitely not be targeted though. I don't know of a website that has your requirements but that is a golden idea. Someone should create one.

for others benefit i came across sponsoredtweets.com, which is close to what i was looking for. Also found that apparently it's against the FB TOS so likely not going to find a big marketplace for this (just have to find the willing individuals).
