How to find where to guestblogg

Hi, i need to find around 50-100 sites in specific niche where i could guestblog. Sites must have PR2+. I can pay for posts, and i give my own content. Any1 who can help me - pm.

There are lots of ways. There's the now-popular 'myblogguest' (G**gle it). There are plenty of people who offer guest posting services. You can G**gle "niche keyword" with "guest post" "write for us" "contribute", etc...
