I've started to contact local bloggers in the niche I'm now working on, with the intent of getting either guest blog posts or getting them to set-up some affiliate banners on their sites. For the banners I'm planning to make either my own "affiliate system" or set it up via third party, not sure yet, but the blog posts are easier to be handled on pay-per-post basis. But how much should I pay for them? Let's say the blogs are PR2, rank quite well (within top five) in local Google for some of the most searched keywords with xx-xxx UV's a day. I'd just post like 500 word articles, with 2-3 links back to my site.
