why don,t you try article marketing instead of blog post backlink

flexnds said:myblogguest.com is pretty good, and free too.. You could also outsource a company to find blogs to guest post on. This has worked for me and is nice because the blog owners will give you a permanent contributor account where you can go back and link to new sites as well. Over time, quick high quality backlinks are a breeze.
