This used to be my main website a few years ago, but at the moment it's a very nice aged domain with only white hat SEO behind it. I'll be frank and say that at the moment it is not getting much traffic (100-150 uniques/ day) because I haven't updated it in a while, but other than that it is a gold mine. Your blog post with 2 do follow links will go on the homepage (PA 36 DA 24) and PR 3. As you can see, I have only sold 1 blog post before, everything else was my content and there are very few outgoing links. Relevant sites only and original content please. I truly think that this is one of those gold mine opportunities to get a backlink on a good quality Google friendly website. It's not cheap, but if you do your research you will find that it's worth it.
